Hello student,
The coefficient of restitution is given by:
\text{Coefficient of Restitution } (C_{R}) = \frac{\text{Relative Speed After Collision}}{\text{Relative Speed Before Collision}}
Hence,
Relative Speed after collision would be given by:
\text{Relative Speed After Collision}=\text{Coefficient of Restitution } (C_{R}) \times {\text{Relative Speed Before Collision}}=e\times v
For finding the velocity, you can use the conservation of momentum and the coefficient of restitution.
