Energy and Block Essays
Energy and Block Essays Energy and Block Paper Energy and Block Paper Assignment Physics 1 1 . Two carts, one twice the mass of the other, experience the same force for the same time. What is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact, the block slides 7. 5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0. 60, what was the speed of the bullet immediately before impact? You have to use the conservation of the total energy of the system to do this problem: Initially, you have, in the total of your system, a bullet that is moving at a certain speed and a block that is stationary: Initial total energy = Potential Energy + Kinetic Energy + Elastic Energy There is no potential energy nor is there a spring in the system so no elastic energy. Initial total energy = Kinetic Energy. Since the only thing that is moving in the system is the bullet, then you calculate the kinetic energy of the system at the initial state (before the bullet hits the block): Kinetic energy = 1/2mv2 where m = 0. 012kg so kinetic enery = . 5 * 0. 012 * 0. 6v2 We dont know the initial velocity of the bullet because that is what we are trying to find. Now, you say that Initial Energy of the system = Final energy of the system because no Energy is lost or created, all energy is merely transfered or transformed. Initial Energy = Final Energy Final Energy: At the end, you have: A block with a bullet lodged inside it that is not moving. Therefore No Kintetic Energy, No Pot ential Energy and no Elastic Energy. However, your block did Work in order to combat the friction force and to move the block over a distance of 7. 5 meters. This energy was lost in the friciton and was expulsed as heat when the block was moving. So final Energy = Work done to move the block from O to 7. 5 meters. Work = Force * distance where distance is 7. 5 meters The force is the friction force because that is what the block had to combat in order to move. Friction force = u*N N = (mass of bullet + mass of block)* 9. 81 u = 0. 65 F = 0. 65 * 0. 012 * 0. 1 * 9. 81 = 7. 23918 Newtons = 7. 24 N Work = Force * distance = 7. 24 * 7. 5 = 54. 3 Joules So initial energy = final energy 0. 006V2 = 54. 3 v2 = 9050 v = 95. 13148795220224032296947867491 v = 95 m Is So the bullet was moving at 95 m/s right before it hit the block. 3. A ball bounces upward from the ground with a speed of 14 m/s and hits a wall with a speed of 12 m/ s. How high above the ground does the ball hit the wall? Ignore air resistance. 4. A 200 g mass is attached to a spring of spring constant k. The spring is compressed 15 cm from its equilibrium value. When released the mass reaches a speed of 5 m/s. What is the spring constant (in N/m)? 5. A 34-g bullet traveling at 120m/s embeds itself in a wooden block on a smooth surface. The block then slides toward a spring and collides with it. The block compresses the spring (k=100 N/m) a maximum of 1. 25 cm. Calculate the mass of the block of wood. 6. If a force of 300N is exerted upon a 60 kg mass for 3 seconds, how much impulse does the mass experience? 7. An 80-kg man and his car are suddenly accelerated from rest to a speed of 5 m/s as a result of a rear-end collision. Assuming the time taken to be 0. 3s, find: a) the impulse on the man and b) the average force exerted on him by the back seat of his car. 8. An airplane propeller is rotating at 1900 rev/min. a. Compute the propellers angular velocity in rad/s. b. How long in seconds does it take for the propeller to turn through 30. 0 degrees? 9. A disk with a 1. 0-m radius reaches a maximum angular speed of 18 rad/s before it stops 30 revolutions after attaining the maximum speed. How long did it take the disk to stop? 10. A net torque of 36 N. m acts on a wheel rotating about a fixed axis for 6 s. During this time the angular speed of the wheel increases from O to 12 rad/s. The applied force is then removed, and the wheel comes to rest in 75 s. a. What is the moment of inertia of the wheel? b. What is the magnitude of the frictional torque? c. How many revolutions does the wheel make?

How did teddy roosevelts life prepare him to build panama canal Essay
How did teddy roosevelts life prepare him to build panama canal - Essay Example The Panama Canal was a project by the French that would save the long journey from the Atlantic to Pacific via South America and which took months to get across from. Just as the Suez Canal had attracted investors, the Panama Canal was believed to be a viable project for future investors as well. Due to the bad weather and wild animals including snakes and insects that caused malaria, thousands of workers died and millions were used without any much work being completed and the canal was left unfinished by the French. Once he became president, Roosevelt picked up the project in 1902 and they reached an agreement of $40 million to buy the rights from the French and agreement reached with Panama of $10 million which secured the Canal Zone rights to build. This was not so smooth a deal as US had to go to war with Columbia over Panama and US won amid bribery of soldiers to surrender the war and it made Panama a country with its own sovereign rights from Columbia and hence accepting the deal from the US of the rights in exchange for the money to build their country (Vander Hook,

Warehouse Layout Planning Research Paper Example | Topics and Well Written Essays - 750 words
Warehouse Layout Planning - Research Paper Example The design of a warehouse should be capable of maximizing the utility of space while simultaneously allowing for sufficient circulation paths for both material handling equipment, for instance, forklift trucks and warehouse personnel. As a consequence, it is critical for warehouse planning and design to take advantage of height allowances through the use of higher bays. In order to facilitate flexibility in warehouse planning and design, it is vital to make use of alternative methods for handling material. These methods typically influence construction and planning aspects such as aisle widths, need for the inclusion of mezzanine space, egress design and lighting design (Christopher & Towill, 2001). Warehouses should typically be designed by taking into consideration both present and future needs in order to allow for changes in enterprise growth, size of warehouse spaces and population and size of the office. It is vital for warehouse space to be easily adaptable to fit varying func tions, for instance, office levels and computer centers. Effective site design accommodates the need for future loading docks, car parking spaces and truck space. In order to achieve this, enterprises need to address techniques for handling material and business practices, for instance, just-in-time storage. This involves the inclusion of roof designs with extra structural capacity that is built-in to facilitate the addition of supplementary rooftop equipment. In order to ensure that the future supplementary space is effective with regard to handling future material, the design should encompass fire protection capacities (Cormier & Gunn, 1992). This will allow for the accommodation of storage materials that have an increased level of fire hazard, particularly with regard of high plastic products. Flexibility can be built into warehouse design and planning to contain future changes through the implementation of scenario planning, which ultimately results enhanced flexibility. Scenari os can be constructed either through modeling or simulation to take into consideration a variety of situations through which the design flexibility can be assessed effectively. Such scenarios include, for instance, alternative growth anticipations, unusual peak provisions and alterations in order profiles. This typically requires the use of simulation tools that can prove effective. These simulation tools include general simulation packages adaptable for warehousing and specified warehousing simulation packages. These packages include some that can be purchased directly from suppliers and others available through equipment suppliers, suppliers of warehouse management systems and consultancies (Christopher & Towill, 2001). Since not all tools are applicable in all situations, it is critical that an enterprise adopts the appropriate simulation tool for its flexibility and future needs. For instance, a certain modeling simulation cannot offer accurate answers for certain projects, espe cially where the enterprise is experienced fundamental changes. Although scenario planning is effective, it is not an endeavor to forecast the future. This means that drawing scenarios that predict future events will prove ineffective in the long term since peopleââ¬â¢s perceptions typically influence what they consider as the reality. Predictions for the future

Beowulf and Grendel Essay Example for Free
Beowulf and Grendel Essay The animation used for the movie, Beowulf was simply superb. I thought the characters were human but after a while, I noticed that they move quite differently so I learned that it was actually a motion captured film, like the ones used in Polar Express and Monster House. The effects were good, and the characters really looked like the actors who played them. Itââ¬â¢s amazing what technology can do these days. As for the story, I think some scenes are really violent and brutal. Like the part when Grendel, the monster, tore the head of one of the soldiers and ate it, it was disgusting. Some parts were also rated PG. ut overall, I think the plot was good. The character of Beowulf was very brave and courageous. From the beginning of the story, we can already tell that he is a hero and that he practices the code of honor (whatever that is). He was willing to sacrifice himself to save his people and the kingdom. I think he is also wise as the king. He didnââ¬â¢t fight the soldier who was trying to kill him, instead, send him off saying ââ¬Å"He has a story to tellâ⬠. But the protagonists also have some poor qualities. For one, he didnââ¬â¢t think of the consequences when he gave in to Grendelââ¬â¢s motherââ¬â¢s advances. He also lied to king Hrothgar and his people when he told them that he killed Grendelââ¬â¢s mother. He did all that just so that he could have wealth and the crown. I also didnââ¬â¢t like the fact that he took a mistress, when his wife was still there. I think Queen Wealtheow is a wise and beautiful queen, what more could he ask for? Also, I think Ursula, the concubine, didnââ¬â¢t really love Beowulf. She was just submitting herself to him because he is of course, the king. I think the historical accuracy was good, the costume and the traditions; they even had the right accents.

Fitzgeralds The Great Gatsby and the Tragic Hero Essay -- Great Gats
Fitzgerald's The Great Gatsby and the Tragic Hero à à à à Aristotle invented a list of criteria in an attempt to determine the exact definition of a tragic hero.à The list states the following - the tragic hero must cause his own down fall; the tragic hero's fate is undeserved; the tragic hero's punishment exceeds his crime; the tragic hero must be a great and noble person according to the standards of the current society.à In Fitzgerald's The Great Gatsby, Jay Gatsby can be defined as a tragic hero who possesses all of the aforementioned traits.à à Jay Gatsby's main desire in life is to become a member of high society, respected more than anyone else.à Gatsby has taken steps to ensure that this desire becomes a reality.à He has accumulated wealth, power, and influence, all in an attempt to create the sparkling image of a successful man.à Although Gatsby's friend Nick is "inclined to reserve all judgements" (1), Gatsby is a strong, unselfish idealist.à Gatsby is a romantic dreamer who wishes to fulfill his ideal by gaining wealth in hopes of impressing and eventually winning the heart of the mat... ...his vision, until his death. Daisy indirectly causes Gatsby's death, making her more than ever, unworthy of Gatsby's affections. Ironically, Gatsby lived for Daisy and up to his death, believed and had faith in her and his vision. à Works Cited Dillon, Andrew. "The Great Gatsby: The Vitality of Illusion."
