Problem (4) The motor at C pulls in the cable with an acceleration ac = 3t² m/s², where t is in seconds. The motor at D draws in its cable at ap = 5 m/s². If both motors start at the same instant from rest when d = 3 m, determine: B A -d=3m- (a) the time needed to get to d = 0, and (b) the relative velocity of block A with respect to block B when this occurs.
