The solid rubber balls A and B having masses 200 and 400 gm respectively are moving in opposite directions with velocity of A equal to 0.3 m / s . After collision the two balls come to rest, then the velocity of B is

Two solid balls A and B having masses 200 g and 400 grespectively are moving in opposite direction with velocity of A equal to 0.3 m//s. After the collision the two balls come to rest. The velocity of B before collision is :

Two solid subber balls A and B having masses 0.2 and 0.4 are moving in opposite directions with velocity of A equal to 0.3 ms^-1 After collission, the two balls come to rest when the velocity of B is

Two balls A and B of masses 0.3 kg and 0.2 kg respectively are moving along positive X-axis and negaive X-axis with velocities 2.0 m // s. They collide and thereafter move in the directions opposite to their original directions. Find the velocities of A and B after collision. Also, calculate total K.E. of the ball before and after collision.
