Effective coefficient of kinetic friction between wheel-rag

Reference no: EM13547387

A wheel having a radius 0.50 m and inertia of 11.7 kg · m2 is rotating freely at 54 rev/min. The wheel can be stopped in 4.0 s by pressing a rag against the rim and exerting a radially inward force of 75 N. Find the effective coefficient of kinetic friction between the wheel and rag.
