The pulley has radius R and moment of inertia I. The rope does not slip over the pulley. The coefficient of friction between block A and the tabletop is 4k. the system is released from rest, and block B descends. a) Use energy methods to calculate the speed of block B as a function of the distance d that it has descended. b) Use forces and torques to calculate the speed of block B as a function of the distance d that it has descended.
