The velocity of the second ball after the collision is
Explanation:
We have conservation of momentum
The mass the first ball is
The velocity of the first ball before the collision is
The mass of the second ball is
The velocity of the second ball before the collision is
The velocity of the first ball after the collision is
Therefore,
The velocity of the second ball after the collision is
