Box A and box B are connected by a string that passes over a massless and friction-free pulley having a moment of inertia of I about its axis of rotation as shown below. The mass of box A is greater than that of box B. The two boxes are separated by a vertical distance 2h and released from rest. (a) Determine the translational speeds of the boxes as they pass each other. (b) What is the angular speed of the pulley at this instant?
