The pulley in the figure (Figure 1) has radius R and a moment of inertia I. The rope does not slip over the pulley, and the pulley spins on a frictionless axle. The coefficient of kinetic friction between block A and the tabletop is mu_k . The system is released from rest, and block B descends. Block A has mass m_A and block B has mass m_B Use energy methods to calculate the speed of block B as a function of the distance d that it has descended. Express your answer in terms of the variables m_A, m_B, R, I, mu_k, d and appropriate constants.

The pulley is 14 cm in diameter and has a mass of 2.9 kg.
The two blocks in the figure(Figure 1) are connected by a massless rope that passes over a pulley. The pulley is 14 cm in diameter and has a mass of 2.9 kg. As the pulley turns, friction at the axle exerts a torque of magnitude 0.55 N.m. Part A If the blocks are released from rest, how long does it take the 4.0 kg block to reach the floor?
