Kinetic friction among the wheel and the wet rag

Reference no: EM13661492

A potter's wheel having a radius 0.45m and a moment of inertia 10.2kg·m2 is rotating freely at 55 rev/min. The potter can stop the wheel in4.0 s with pressing a wet rag against the rim and exerting a radically inward force of 71 N. Discover the effective coefficient of kinetic friction among the wheel and the wet rag.
