A 1kg ball moving at 12ms^(-1) collides head on with a 2kg ball moving in the opposite direction at 24m/s. The velocity of each ball after the impact, if the coefficient of restitution is 2/3, is

A 1kg ball moving at 12ms^(-1) collides head on with a 2kg ball moving

1.	A 1kg ball moving at 12ms^(-1) collides head on with a 2kg ball moving in the opposite direction at 24m/s. The velocity of each ball after the impact, if the coefficient of restitution is 2/3, is
