A solid cylinder (I=12MR2) potter's wheel is a thick stone of radius 7 m with mass 5 kg. It freely rotates at 9 radian per second. The potter press a wet rag against the rim and exert a radially inward force of 10 N. If the coefficient of kinetic friction between the rag and the wheel is 0.6, find the time needed for the wheel to stop in seconds.
