A thin, uniform rod of mass M and length L is at rest on a smooth horizontal surface. A particle of same mass M collides with the rod at one end perpendicular to its length with velocity `V_(@)` and sticks to it. C is the middle point of the rod and D is a point at a distance of L/4 from end A. the time taken by the rod turn through `90^(@)` after collisions.
