A disk with a mass of 18.5 kg, a diameter of 36.5 cm, and a thickness of 6.09 cm is mounted on a rough horizontal axle as shown on the left in the figure. (There is a friction force between the axle and the disk). The disk is initially at rest. A constant force, F = 60.7 N, is applied to the edge of the disk at an angle of 37.0°, as shown on the right in the figure. After 2.00 s, the force is reduced to F = 21.7 N, and the disk spins with a constant angular velocity.
