You have a grindstone (a disk) that is 98.0 kg, has a 0.335-m radius, and is turning at 100 rpm, and you press a steel axe against it with a radial force of 23.6 N. Assuming the kinetic coefficient of friction between steel and stone is 0.192, calculate the angular acceleration of the grindstone.

Explanation:

From the question we are told that:

Mass

Radius

Angular velocity

Radial force of

Kinetic coefficient of friction  

Generally the equation for Kinetic Force is mathematically given by

Generally the equation for Torque on Center is mathematically given by

Where

Therefore

Therefore Angular acceleration of the grindstone is

helium

oxygen

neon

sodium
