An electric motor can accelerate a Ferris wheel of moment of inertia I = 19500 kg·m2 from rest to 9.4 rev/min in 12.0 s. When the motor is turned off, friction causes the wheel to slow down from 9.4 to 7.4 rev/min in 10.0 s.

(a) Determine the torque generated by the motor to bring the wheel to 9.4 rev/min.

N·m

(b) Determine the power that would be needed to maintain this rotational speed.
