You have a horizontal grindstone (a disk) that is 95 kg, has a 0.36 m radius, is turning at 92 rpm (in the positive direction), and you press a steel axe against the edge with a force of 21 N in the radial direction.
Randomized Variablesm = 95 kg
r = 0.36 m
f = 92 rpm
F = 21 N
kinetic coefficient of friction between steel and stone is 0.20,
What is the number of turns, N, that the stone will make before coming to rest?
