Academics

A potter's wheel having a radius 0.45 m and a moment of inertia 10.7 kg·m2 is rotating freely at 50 rev/min. The potter can stop the wheel in 5.0 s by pressing a wet rag against the rim and exerting a radially inward force of 75 N. Find the effective coefficient of kinetic friction between the wheel and the wet rag.
