13. A grindstone in the shape of a solid disk with diameter 0.520 m and a mass of 50.0 kg is rotating at 850 rev/min. You press against the rim with a normal force of 160 N (Fig. 10.44), and the grindstone comes to a rest in 7.50 s. Find the coefficient of friction between the axe and the grindstone. You can ignore friction in the bearings. (Dynamics method) LOON 850 vev/mn F160 N m= 50.0 kg Suks 520m' I ΣF=ma 2X= Ia [2=3m ²xx t=79 850ul-7 rad
