A mass of 500 kg is being lifted at uniform speed of 1.5 m/s by a winch driven by a motor running at a speed of 1000 r/min. The moments of inertia of the motor and winch are 0.5 and 0.3 kg^2, respectively. In the absence of the mass, the motor develops a torque of 100 Nm at a speed of 1000 r/min. Calculate a) the equivalent moment of inertia referred to the motor side; b) the motor torque.
