PhysicsNEET 2022Torque, angular momentum and their conservation

System of Particles and Rotational Motion

The angular speed of a flywheel moving with uniform angular acceleration changes from 1200 rpm to 3120 rpm in 16 seconds. The angular acceleration in $rad/ s^{2}$ is:

A. $104 π$
B. $2 π$
C. $4 π$ ✓
D. $12 π$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
