(a) Compute the torque developed by an industrial motor whose output is 150 kW at an angular speed of 4000 rev/min.

(b) A drum with negligible mass, 0.400 m in diameter is attached to the molar shaft, and the power output of the molar is used to raise a weight hanging from a rope wrapped around the drum. How heavy a weight can the motor lift at constant speed?

(c) At what constant speed will the weight rise?
