## Homework Statement

From the given picture, we know:

VA before collision

VB before collision

the radius to the center of mass of each car from the collision point P

e

the masses of both

the mass moment of inertia of both

We must find the velocities of the centers of mass of each car and their respective angular velocity.

## Homework Equations

e = Vbp(y)2 - Vba(y)2 / Vap(y)1 - vbp(y)1

equations relating Vap to Va and Vbp to Va

(Hp)1 = (Hp)2

## The Attempt at a Solution

I have worked out all of the relations and equations until I have a correct (Hp)1 = (Hp)2 formula. I have it in terms of omega(A) and Vay after impact.

The equation I have is correct since it works with the answers given in the problem. However, I cannot for the life of me figure out how to relate omega(A) to Vay after impact. I tried finding the instantaneous center of zero velocity, but that introduced more unknowns. Maybe there is a different relationship I missed between other variables which can be converted into terms depending on omega(A) and Vay?
