The disk-shaped pulley of mass 10.0kg has a radius R and a moment of inertia I turns on a frictionless bearing. The rope does not slip over the pulley.
a) Find the work done by the frictional force, if the system drops 0.60m the coefficient of kinetic friction between the table and the 5.00kg block is 0.35
b) How fast is the system moving after dropping 0.6m?

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.
