A uniform rod of mass 2m and length l is pivoted at a points S which is 
from one end and the rod is free to rotate in a vertical plane as shown. A particle of mass m strikes the rod elastically at its mid point C. Before the collision particle was moving horizontally with speed u. Find
- the speed of particle just after the collision.
- angular velocity of the rod just after the collision
- impulse imparted by the hinge during the collision.
- none
The correct answer is: none
