Question: The motor at C pulls in the cable with an acceleration ac= (3t)2 m/s, where t is in seconds. The motor at D draws in

The motor at C pulls in the cable with an acceleration ac= (3t)2 m/s, where t is in seconds. The motor at D draws in its cable at aD = 5m/s2. If both motors start at the same instant from rest when d = 3m, determine (a) The time needed for d = O, and (b) The relative velocity of block A with respect to block B when this occurs.
