A potter's wheel having a radius 0.53 m and a moment of inertia of 14.9 kg · m2 is rotating freely at 46 rev/min. The potter can stop the wheel in 4.0 s by pressing a wet rag against the rim and exerting a radially inward force of 72 N. Find the effective coefficient of kinetic friction between the wheel and the wet rag.
