I tried solving this question by applying conservation of momentum. Like this,speed=20/5=4m/sSo,(v1+4)40+(-v2+4)40=0But,i am getting wrong answer!Please answer this question and also tell me where i was doing wrong.

the final velocity of system = 20/5 = 4m/s

total final momentum = (40+40+20)*4 = 400kg.m/s

V1(wrt ground) = V1+4

V2 (wrt groung) = V2-4

initial momentum = final momentum

40*V1-40*V2 = 400kg.m/s

V1-V2 = 10.
