Arotating wheel requires 2.90-s to rotate through 37.0 revolutions. its angular speed at the end of the 2.90-s interval is 97.2 rad/s. what is the constant angular acceleration of the wheel?

Angular acceleration,

Explanation:

It is given that,

Displacement of the rotating wheel,

Time taken, t = 2.9 s

Initial speed of the wheel,

Final speed of the wheel,

Let is the angular acceleration of the wheel. Using the third equation of kinematics to find it as :

So, the angular acceleration of the wheel is . Hence, this is the required solution.
