A potter's wheel having a radius 0.48 m and a moment of inertia of 12.3 kg · m2 is rotating freely at 55 rev/min. The potter can stop the wheel in 7.5 s by pressing a wet rag against the rim and exerting a radially inward force of 65 N. Find the effective coefficient of kinetic friction between the wheel and the wet rag.
