An electric motor can accelerate a Ferris
wheel of moment of inertia 12200 kg · m2 from
rest to 11.1 rev/min in 12.5 s. When the mo-
tor is turned off, friction causes the wheel to
slow down from 11.1 rev/min to 7.61 rev/min
in 8.41 s.
Determine the torque generated by the mo-
tor to bring the wheel to 11.1 rev/min. An-
swer in units of N · m.
