Pulley A and the attached drum B have a weight of 20 lb and a radius of gyration of k_B = 0.6 ft. If pulley P "rolls" downward on the cord without slipping, determine the speed of the .20-lb crate C at the instant s = 10 ft. Initially, the crate is released from rest when s = 5 ft. For the calculation, neglect the mass of pulley P and the cord.
