The object pictured to the right can rotate freely about the axis of rotation shown. The object is initially at rest. At time t=0, a force F, equal to 7.50N, is applied at a distance of r = 0.900 m from the axis of rotation as
shown. The force is applied for 5.0 s. During this time, the object rotates through 19.9 revolutions. Assume that for t > 5.0 s, the net torque is zero. Find the angular acceleration during the time the force is applied
