Question

A rod of length 2a is constrained to move with its ends on the perimeter of a circle of radius . This circle lies in the horizontal plane and is fixed. A small insect whose mass is equal to that of the rod moves along the rod, starting from its mid-point and maintaining a constant relative speed V, then show that in time t, the rod will turn through an angle $\Theta = \frac{1}{\sqrt{3}}\tan^{-1}(\frac{vt}{a})$
