You have a grindstone (a disk) that is 80 kg, has a 0.37 m
radius, and is turning at 110 rpm, and you press a steel axe
against it with a radial force of 15 N. (a) Assuming the kinetic
coefficient of friction between steel and stone is 0.2, calculate
the angular acceleration of the grindstone. α unit rad/s^2 Correct
(b) How many turns will the stone make before coming to rest?
