A disk of mass M = 2.0 kg and radius R = 0.25 m is free to rotate about its center. Two forces, F1 = 1.0 N and F2 = 4.0 N are applied tangentially to the disk, as shown. 1. How fast is a point located on the edge of the disk moving at t = 2.5s? 2. How many revolutions has the disk made after t = 2.5 s, assuming it starts from rest?
