Question

collar A and block B are connected by a cable crossing over three pulleys C,D, and E as shown. pulleys C and E are fixed, while D is attached to a collar which is pulled downward with a constant velocity of 3in/s. at t=0, collar A starts moving downward from position K with a constant acceleration and no initial velocity. knowing that the velocity of collar A is 12 in/s as it passes through point L, determine the change in elevation, the velocity, and the acceleration of block B when collar A passes through L
