An 8-kg cylinder C is released from rest in the position shown and drops onto a 5-kg platform A which is at rest and is supported by an inextensible cord attached to a 5-kg counterweight B. Knowing that the coefficient of restitution between cylinder C and platform A is 0.8 and that the velocity of C is zero immediately after the first impact, determine

(a) The velocities of C and A immediately before the second impact,

(b) The velocities of C and A immediately after the second impact.
