A cable passes over a pulley. Because the cable grips the pulley and the pulley has nonzero mass, the tension in the cable is not the same on opposite sides of the pulley. The force on one side is 117 N, and the force on the other side is 95 N. Assuming that the pulley is a uniform disk of mass 1.55 kg and radius 1.049 m, find the magnitude of its angular acceleration. [For a uniform disk, I
