Two balls with masses m_(1) = 3kg and m_2 = 5kg have intial velocities V_1 = 5ms^(-1)towards east and V_2 = 5ms^(-1)towards North. They collide at the origin. The ratio of velocity of CM. 3s before collision to that 5s after collision is.........

Two balls with masses m_(1) = 3kg and m_2 = 5kg have intial velocities

1.	Two balls with masses m_(1) = 3kg and m_2 = 5kg have intial velocities V_1 = 5ms^(-1)towards east and V_2 = 5ms^(-1)towards North. They collide at the origin. The ratio of velocity of CM. 3s before collision to that 5s after collision is.........
