The pulley has radius R and 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 the table top and block A 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 that it had descended.

I'm not sure how to incorporate hte moment of inertia and the rotational motion of the pulley.

Could someone please help.

Thank you.
