# Angular Acceleration of a Solid Disk

CLMECH-11XVSK

A uniform, solid disk of mass $1.2$ $kg$ and radius $0.21$ $m$ is free to rotate in a horizontal plane about a vertical axis that passes through the disk's center of mass.

If a torque of 0.08 N$\cdot$m is applied to the disk, how much is its angular acceleration?

A

$1.5 \space \cfrac{rad}{s^2}$

B

$0.32 \space \cfrac{rad}{s^2}$

C

$2.1 \space \cfrac{rad}{s^2}$

D

$3.1 \space \cfrac{rad}{s^2}$
