Question: A motor spins a disk (I disk = 25.7 kg*m 2 ) with a torque of 41 N*m, and a 12 N frictional force acts

A motor spins a disk (Idisk = 25.7 kg*m2) with a torque of 41 N*m, and a 12 N frictional force acts on the disk at a radius of 1.6 m. Attached to the disk at a radius of 1.3 m is a 5 kg mass. What is the magnitude of the angular acceleration in rad/s2 of the system?
