The ball A of weight { W }_{ A } is thrown so that when it strikes the block B of weight { W }_{ B } it is traveling horizontally at speed v. If the coefficient of restitution between A and B is e, and the coefficient of kinetic friction between the plane and the block is { μ }_{ k } , determine the time before block B stops sliding. Given: { W }_{ A } = 1 lb , { μ }_{ k } = 0.4 , { W }_{ B } = 10 lb , v = 20 ft/s , g = { 32.2ft/s }^{ 2 } , e = 0.6
