Acable passes over a pulley. because the cable grips the pulley and the pulley has non- zero mass, the tension in the cable is not the same on opposite sides of the pulley. the force on one side is 167 n, and the force on the other side is 42 n. assuming that the pulley is a uniform disk of mass 1.06 kg and radius 0.433 m, find the magnitude of its angular acceleration. for a uniformi disk, i = (1/2) m,2.1 answer in units of rad/s
