Q1. A potter's wheel having a radius 0.47 m and a moment of inertia 10.9 kg•m2 is rotating freely at 46 rev/min. The potter can stop the wheel in 7.0 s by pressing a wet rag against the rim and exerting a radically inward force of 68 N. Find out the effectual coefficient of kinetic friction between the wheel and the wet rag.
