Two ball A and B are approaching each other with the velocities 4.5 m/s and 7.2 m/s respectively. The man of ball A is 3.2 kg
While that of ball is 5.4 kg. Fine the velocity of the two bodies after the impact assuming that the collision is perfectly inelastic.
Let us choose the positive axis direction along the velocity of the ball B. Momentum before the impact is , and after is , where is unknown. According to the conservation of momentum , from where
