You have a grindstone a disk that is 800 kg has a 349-m, Ask an Expert

Academics

You have a grindstone ( a disk) that is 80.0 kg, has a .349-m radius, and is turning at 104.0 rpm, and you press a steel axe against it with a radial force of 24.0 N. Assuming the kinetic coefficient of friction between steel and stone is 0.196.

a) Calculate the angular acceleration of the grindstone.

b) How many turns will the stone make before coming to rest?
