A solid cylindrical disk is caused to rotate about a stationaryaxis which passes through the center of gravity of the disk. Theforce that produces rotation is applied to the rim of the disk bymeans of a cable which is wound around the disk and is attached toa body. The radius of the disk is 2.5 ft the weight of the disk is800 lb and the weight of the body is 300 lb. When the body issupported in the position shown the body and the disk are at rest.If the support tor the body is taken away the disk will rotatewithout friction while the body moves downward under the action ofits weight. The angular velocity of the disk after the body hasmoved 5 tt from the position shown would be
