#### Solution Preview

Remember that liner momentum is always conserved.

Mass m1 of velocity v1 collides with a mass m2 of velocity v2, after collision, mass m1 will have velocity v3 and mass m2 will have velocity v4. And also,

m1v1 + m2v2 = m3v3 + m4v4

...

#### Solution Summary

A sphere striking another sphere for conservation of momentum is provided. The coefficient of restitution is determined. Clear explanations and all mathematical steps are provided.
