A potter's wheel-a thick stone disk of radius 0.500 m and mass 115 kg-is freely rotating at 50.0 rev/min. The potter can stop the wheel in 6.00 s by pressing a wet rag against the rim and exerting a radially inward force of 71.0 N. Find the effective coefficient of kinet friction between the wheel and rag.
