The two blocks in the figure are connected by a massless rope that passes over a pulley. The pulley is 17 in diameter and has a mass of 1.9 . As the pulley turns, friction at the axle exerts a torque of magnitude 0.40 .
If the blocks are released from rest, how long does it take the 4.0 kg block to reach the floor?
