rotational-motion

Question: A rigid body is rotating with variable angular velocity $(a-bt)$ at any instant of time t. The total angle subtended by it before coming to rest will be (a and b are constants)

1) $\frac{(a-b)\,a}{2}$

2) $\frac{{{a}^{2}}}{2b}$

3) $\frac{{{a}^{2}}-{{b}^{2}}}{2b}$

4) $\frac{{{a}^{2}}-{{b}^{2}}}{2a}$
