Hi all

V^2 = u^2 + 2as
V = 8.85 m/s which will be intial veloctiy befor hits the second body
Bu using
e(u1 - u2 )=V2 -V1
m1u1 +m2u2 =m1v1+m2v2
for the body which is 20 N
mass 20.3
u1 = 8.86 0m/s
V1 after collision = 0 m/s
for the second body which is 40 N
mass = 4.077
u2 = 0
v2 we will find final velocity after collion
m1u1 +m2u2 =m1v1+m2v2
2.03 X 8.86 + 4.077 X 0 = 2.03X(0) + 4.077V2
