A motor provides the torque necessary to keep a gear turning at
constant angular velocity, overcoming friction between the gear and
the axle.
The gear can be modeled as a disk, with mass 2 kg, and radius
rg = 0.2 m. The force of friction can be
modeled as a single force, acting at the outer edge of the axle, at
position ra = 0.02 meters, with force of
fk = 10 N.

A ceiling fan is spinning with an angular velocity of +10RAD /s. It then comes to a stop over a brief period of time. During this time, its angular displacement is +8.7RAD. The blades of the fan extend 0.9 m from the center. (a) Determine the average angular acceleration. (b) Determine the time during which it comes to rest. (c) How far (in meters) does the tip of each blade travel during this time?
