A block of mass $m$ is placed on a smooth horizontal surface. A force making an angle $\theta$ with the horizontal starts acting on the block. The magnitude of the force is constant but its direction with the horizontal changes as $\theta = a+ bs$, where $a$ and $b$ are constants and $s$ is the distance covered by the block. If $|F| = 2mb$, find the velocity of the block as function of the angle $\theta$ .
