Plates A and B each have a mass of 4 kg and are restricted to move along the frictionless guides. If the coefficient of restitution between the plates is e = 0.7, determine (a) the speed of both plates just after collision and (b) the maximum deflection of the spring. Plate A has a velocity of 4 m/s just before striking B. Plate B is originally at rest.
[A]. vA2 = 0.857 m/s, vB2 = 4.86 m/s, x = 0.434 m
[B]. vA2 = 0.600 m/s, vB2 = 3.40 m/s, x = 0.304 m
[C]. vA2 = 0, vB2 = 4.00 m/s, x = 0.358 m
[D]. vA2 = 0.327 m/s, vB2 = 3.67 m/s, x = 0.329 m
