A wheel in the form of a uniform disk of radius 23.0 cm and mass 1.40 kg is turning at 840 rev/min in frictionless bearings. To stop the wheel, a brake pad is pressed against the rim of the wheel with a radially directed force of 130 N. The wheel makes 2.80 revolutions in coming to a stop. Find the coefficient of friction between the brake pad and the rim of the wheel
