Q. A potter's wheel having a radius 0.55 m and a moment of inertia 14.8 kg•m2 is rotating freely at 52 rev/min. The potter can stop the wheel in 5.0 s by pressing a wet rag against the rim and exerting a radically inward force of 67.00N. Determine the effective coefficient of kinetic friction between the wheel and the wet rag.
