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
