Total velocity =v.
Velocity distributed uniformly that = v.
2 ball each has v/2.
Velocity distributed uniformly that = v.
2 ball each has v/2.

It should be perfectly inelastic material then only V/2 answer will be correct.

Initial velocity = v.
Given condition that both balls are moving.
Hence v/2.
Given condition that both balls are moving.
Hence v/2.

m1u1+m2u2=(m1+m2)v2.
u2=0 as it's stationary.
So,
mu/2m=v2,
1u/2=v2.
u2=0 as it's stationary.
So,
mu/2m=v2,
1u/2=v2.

Elastic material means that the ability to regain original position.

Conservation of momentom
mv=m1v1+m2v2
mv=mv`+mv`
v`=v/2
mv=m1v1+m2v2
mv=mv`+mv`
v`=v/2

The velocity will be transferred from the 1st body to the second.

Perfectly elastic materials e (coefficient of restitution) =1.

Total mass = mv'+mv'.
mv = mv'+mv'.
v = 2v'.
And:v' = v/2.
mv = mv'+mv'.
v = 2v'.
And:v' = v/2.

For perfectly elastic body the velocity of each body is v/2.
