At a time t = 3.10 s , a point on the rim of a wheel with a radius of 0.200 m has a tangential speed of 50.0 m/s as the wheel slows down with a tangential acceleration of constant magnitude 10.3 m/s2 .

Angular acceleration,

Explanation:

It is given that,

Radius of the wheel, r = 0.2 m

Tangential speed of the wheel,

Tangential acceleration of the wheel,

It is assumed to find the angular acceleration of the wheel. It is given by :

Where

is the angular acceleration of the wheel

So,

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