The double pulley consists of two parts that are attached to one another. It has a weight of 50 lb and a radius of gyration about its center of k_O = 0.6 ft and is turning with an angular velocity of 20 rad/s clockwise. Determine the kinetic energy of the system. Assume that neither cable slips on the pulley.
