A 1.2lb ball A is moving with a velocity vA when it is struck by a2.4lb ball B which has a velocity of vB of magnitude vB = 18 ft/s.Knowing that the velocity of ball B is zero after impact and thatthe coefficient of restitution is 0.8, determine the velocity ofthe ball A (a) before impact and (b) after impact.
