Q. An electrical motor can accelerate a ferris wheel whose moment of inertia is 20,000 kg-m^2 from rest to 10 rev/min in 12 sec. When the motor is turned off, the ferris wheel slows down from 10 to 8 rev/min in 10 sec due to frictional losses. Determine a) the torque generated by the friction forces on the wheel. b) The torque produced by the motor bringing the wheel from rest to 10.0 rev/min. c) The powers necessary to maintain the ferris wheel's rotation speed at a constant 10 rev/min.
