A potter’s wheel, a thick stone disk of radius 0.500 m and mass 100 kg, is freely rotating at 70.0 rev/min. The potter can stop the wheel by pressing a wet rag against the rim and exerting a radially inward force of 35.0 N. If the applied force slows the wheel down with an angular acceleration of 0.875rad/s2 , calculate the torque acting on the wheel and the coefficient of kinetic friction between the wheel and the rag

A student holds a bike wheel and starts it spinning with an initial angular speed of 7.0 rotations per second. The wheel is subject to some friction, so it gradually slows down. In the 10-s period following the inital spin, the bike wheel undergoes 60.0 complete rotations. Assuming the frictional torque remains constant, how much more time ?ts will it take the bike wheel to come to a complete stop? The bike wheel has a mass of 0.725 kg and...
