Answer 1

Answer:

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.
