A fly wheel is accelerated uniformly from rest and rotates through 5 rad in the first second. The angle rotated by the fly wheel in the next second, will be :
Solution
<p>${\theta _1} = {1 \over 2}\alpha (2 \times 1 - 1) = 5$ rad</p>
<p>$\Rightarrow$ $\alpha$ = 10 rad/sec<sup>2</sup></p>
<p>So ${\theta _2} = {1 \over 2} \times \alpha (2 \times 2 - 1) = 15$ rad</p>
