The 1-lb ball A is thrown so that when it strikes the 10-lb block B it is traveling horizontally at 20 ft/s. 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 μ_k = 0.4, determine the time before block B stops sliding. 20 ft/s A B
