A small putty ball of mass 2m is thrown horizonatally at a rod of 3m and lenth L which pivots freely about about fixed axis throught one end . The puty ball is thrown with velocity v at the free end of the rod, to which it sticks ,
1) what is angular velocity of the rod after the putty sticky to it ?
2) which of following quatites of the ball plus rod system are conserved in this collisoin?
