Part A A 4-lb ball A is traveling horizontally at 21 ft /s when it strikes a 10-lb block B that is at rest. If the coefficient of restitution between A and B is e = 0.6, and the coefficient of kinetic friction between the plane and the block is uk = 0.2, determine the time for the block B to stop sliding.
