A grindstone in the shape of a solid disk with diameter 0.520 and a mass of = 50.0 is rotating at = 860 . You press an ax against the rim with a normal force of = 250 (Figure 1) , and the grindstone comes to rest in 7.40 .

Find the coefficient of friction between the ax and the grindstone. You can ignore friction in the bearings.
