A bar of mass m resting on a smooth horizontal plane starts moving due to a constant force F. In the process of its rectilinear motion the angle θ between the direction of this force and the horizontal varies as θ=kx, where k is a constant and x is the distance traversed by the bar from its initial position. The velocity (v) of the bar as a function of the angle θ is
