Aforce of 45 n is applied tangentially to the rim of a solid disk of radius 0.12 m. the disk rotates about an axis through its center and perpendicular to its face with a constant angular acceleration of 140 rad/s2. determine the mass of the disk.

Mass of the disk will be 2.976 kg

Explanation:

We have given force F = 45 N

Radius of the disk r = 0.12 m

Angular acceleration

We know that torque

And

So , here I is moment of inertia

So

We know that moment of inertia

So

m = 2.976 kg

mass and volume are the answers you are looking for
