The angular speed of fly wheel moving with uniform angular acceleration changes from 1200 rpm to 3120 rpm in 16 seconds. The angular acceleration in

\mathrm{rad/}{\mathrm{s}^2}

is:

View answer and explanation

Correct option: C

4\,\pi

Option C (

4\pi

) is correct because the angular acceleration is calculated using the change in angular speed over time, converting rpm to rad/s.
