Question

Blocks A and B are connected by a cord which passes over pulleys and through a collar C. The system is released from rest when x= 1.7 m. As block A rises, it strikes collar C with perfectly plastic impact (e= 0). After impact, the two blocks and the collar keep moving until they come to a stop and reverse their motion. As A and C move down, C hits the ledge and blocks A and B keep moving until they come to another stop. Determine (a) the velocity of the blocks and collar immediately after A hits C, (b) the distance the blocks and collar move after the impact before coming to a stop, (c) the value of x at the end of one complete cycle.
