m = 50.0 kg F = 160 N A grindstone in the shape of a solid disk with diameter 0.520 m and a mass of 50.0 kg is rotating at 810 rev/min. You press an ax against the rim with a normal force of 190 N grindstone comes to rest in 7.10 s. Find the coefficient of friction be- tween the ax and the grindstone. You can ignore friction in the bearings. and the
