A uniform disk of mass M = 750 g, radius r = 28 cm, is free to rotate about an axis going into the paper at point P. The disk is initially at rest. A cord is attached at one end to the rim of the disk and wraps around the rim. At time t =0 s a constant force of 1.05 N is applied to the free end of the cord causing the disk to rotate. a. What is the moment of inertia, I, of the disk? b. What is the angular acceleration of the disk?
