P is an 85 kg diver who leaps off the diving board with an angular momentum of 24 kg·m2/s and curls into a ball to rotate (position A). Their radius of gyration when in the ball is 0.3m. P then fully extends into a headfirst diving position (position B) where their radius of gyration is 1.6m. The time from position A to position B occurs in 0.8 seconds. (You do not need to convert radians to meters) a. What is...

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.
