1. The problem statement, all variables and given/known data Summary: The pulley in the figure 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 [itex]\mu[/itex]k. The system is released from rest, and block B descends. Block A has mass (ma) and block B has mass (mb). Question: 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 ma, mb, R, I, [itex]\mu[/itex]k, d and appropriate constants 2. Relevant equations Conservation of Energy: PEi + KEi = PEf + KEf + frictional work 3. The attempt at a solution (magd) + (mbgd) = maVa2/2 + mbVb2/2 + I[itex]\omega[/itex]2/2 + [itex]\mu[/itex]kmg 0 + (mbgd) = 0 + mbVb2/2 + I[itex]\omega[/itex]2/2 + [itex]\mu[/itex]kmg Is this right?
