Answer:
A thin uniform rod, pivoted at O, is rotating in the horizontal plane with constant angular speed , as shown in the figure.
At time t = 0,
a small insect starts from O and moves with constant sped v, with respect to the rod towards the other end. It reaches the end of the rod at t =T and stops. The angular speed of the system remains
