a solid cylindrical disk is caused to rotate about a stationary axis, which passes through the center of gravity of the disk. the force that produces rotation is applied to the rim of the disk by means of a cable, which is around the disk and is attached to a body. the radius of the disk is 2.5 ft, the weight of the disk is 800 pounds, and the weight of the body is 300 pounds. when the body is supported in the position shown. the body and disk are at rest. if the support for the body is taken away, the disk will rotate without friction while the body moves downward under the action of its weight. the angular velocity of the disk after the body has moved 5 ft from the position shown would be
