Part A A grindstone in the shape of a solid disk with diameter 0.520 m and a mass of 50.0 kg is rotating at 900 rev / min . You press an axe against the rim Find the coefficient of kinetic friction between the axe and the grindstone. with a normal force of 160 N (see the figure below ( Figure 1)), and the grindstone comes to rest in 8.50 s. There is negligible friction in the bearings. VO AEQ ? LL = Submit Request Answer Figure K 1 of 1 m = 50.0 kg Provide Feedback F = 160 N
