1yes. Btw i got it now.
mass of rod = 30 kg
length = 0.8 m
is free to rotate about horizontal axis 'O' passing through its centre.
a particle p of mass = 11.2 kg falls vertically through a height h = 36/245 m and collides elastically with the rod at a distance l/4 from 'O'.
at the instant of collision, rod was stationary.
find angular velocity of rod just after collision.
