Impact Restitution Velocity

Please see attachments to view the question. I am not too sure what calculations I need to perform in order to get the right value.


Solution Preview

We have the coefficient of restitution,
e = -[vb(after) - vc(after)] / [vb(before) - vc(before)]

- where, v1 and v2 are the velocities of the first car and the second car respectively.
ma = mb = mc = m

1) for cars C and A

- here, vc(before) = 4.5 ft/s vc(after) = ?
- vb(before) = 0 ft/s vb(after) =?

We have two unknowns and ...
