The pool ball A travels with a velocity of 10 m/s just before it strikes ball B, which is at rest. If the masses of A and B are-each 276 g,
and the coefficient of restitution between them is e = 1, determine the velocity of ball B just after impact.
4. The 12-kg package A has a speed of 2.5 m/s when it enters the smooth ramp. As it slides down the ramp, it strikes the 34-kg package B which is initially at rest. If the coefficient of restitution between A and Bis = 0.65, determine the velocity of B just after the impact.
A ball of negligible size and mass m is given a velocity of v0 on the center of the cart which has a mass M and is originally at rest. If the coefficient of restitution between the ball and walls A and B is e, determine the velocity of the ball and the cart just after the ball strikes A. Also, determine the total time needed for the ball to strike A, rebound, then strike B, and rebound and then return to the center of the cart. Neglect friction
