An electric motor can accelerate a Ferris wheel of moment of inertia I = 18500kg·m2 from rest to 10.1rev/min in 12.0s. When the motor is turned off, friction causes the wheel to slow down from 10.1 to 8.1 rev/min in 10.0s.
1) Decide the torque generated by the motor to bring the wheel to 10.1 rev/min.
2) Decide the power that would be needed to maintain this rotational speed.
