PART B-CONSERVATION OF MOMENTUM 5. State the Law of Conservation as it pertains to momentum. 6. What is the difference between an elastic and inelastic collision? 7. Suppose you are playing ice hockey in the middle of a totally frictionless frozen pond. can you move yourself to the edge of the pond? Remember that without friction, you won't be able to push against the ice. Explain what you would do and why it would work How 8. A4.5-kg ham is thrown into a stationary 15-kg shopping cart. At what speed will the cart travel if the ham had an initial speed of 2.2 m/s? If the ham hits the cart with 2N of force, how long did the collision between the two last? 9. A 6-kg bowling ball rolling at 5 m/s strikes a stationary 4-kg bowling ball. If Ball #1 is moving forward at 2 m/s after the collision, what is the speed and direction of Ball #2? What is the impulse of the system? If the collision last for .5 seconds, how much force is exerted? 10.Make two event chains showing what happens when a rolling ball (Ball 1) hits a resting batl (Ball 2). Use the phrases: gains momentum, hits Ball 2, is hit by Ball 1, loses momentum, rests, rolls, slows down, and starts rolling. -BALLI BALL 2Explanation / Answer
1. Law of conservation of momentum for a system of collision of 2 or more bodies in an isolated environment, the total momentum before the collision is equal to the total momentum after the collision.
2. In an inelastic collision, the energy is lost and the velocities may not be the same after the collision.
Whereas in an elastic collision the energy remains the same and the velocity are same in magnitude
