A 58-lb sphere A of radius 4.5 in. moving with a velocity of magnitude v0 = 6 ft/s strikes a 5.3-lb sphere B of radius 2 in. which is initially at rest. All surfaces of contact are frictionless. Assuming perfectly elastic impact (e = 1) and no friction, determine the velocity of each sphere immediately after impact.
