A grindstone in the shape of a solid disk with diameter0.520 m and a mass of 50.0 kg is rotating at 850 rev/min. You press anax against the rim with a normal force of 160 N , and thegrindstone comes to rest in 7.50 s. Find the coefficient of friction betweenthe ax and the grindstone. You can ignore friction in the bearings.
