Answer: The pulley in Fig. P9.75 has radius R and a moment
Chapter 9, Problem 9.75(choose chapter or problem)
The pulley in Fig. P9.75 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 mk. The system is released from rest, and block B descends. Block A has mass mA and block B has mass mB. Use energy methods to calculate the speed of block B as a function of the distance d that it has descended.
