Q. A wheel has angular acceleration of $3.0\ rad/s{ec}^{2}$ and an initial angular speed of $2.00\ rad/sec$. In a time of $2\ sec$ it has rotated through an angle (In radian) of

A) 6
B) 10
C) 12
D) 4
Explanation

(b) $\theta = \omega_{0}t + \frac{1}{2}\alpha t^{2} = 2 \times 2 + \frac{1}{2} \times 3 \times (2)^{2} = 10rad$
