Question

Problem 6.53, Ball 1 is moving toward you at 12 m/s , and you decide to throw ball 2 at it to make it reverse its velocity. The balls collide head-on, and the coefficient of restitution for the collision is 0.90. Ball 1 has an inertia of 0.500 kg and ball 2 has an inertia of 0.650 kg . Call the direction of motion in which we throw ball 2 the +x direction.Part A How fast must ball 2 be traveling in order to reverse the velocity of ball 1? Part B What is the initial relative speed of the two balls? Part C How do the balls initially move? Part D What is their reduced inertia? Part E What percentage of the original kinetic energy is convertible? Part F What is the x-component of the final velocity of the ball 1 immediately after the collision? Part G What is the x-component of the final velocity of the ball 2 immediately after the collision?
