answered-by-expert Expert Answer

considering it to be a perfectly elastic collision in one dimension , let the velocity of 1st player be v1 and that of second player be v2 . Use the formulae given below to calculate the velocities of the players :

v1 =  [ ( m1 -  m2 ) u1  /  ( m1 +  m2 ) ]   +  2 m2 u2  /  ( m1 +  m2 ) 

V2 = [  ( m2 - m1 ) u2 /  ( m1 +  m2 ) ]    + 2 m1 u1  /  ( m1 +  m2 ) 

where m1 and m2 are masses of 1st and 2nd players resp. and u1 ,  u2  their velocities.
