AFTER the collision, there is no momentum.
Answered by Damon
Momentum before = momentum after if there is no net force on system

If they were both going at twenty right toward each other (opposite velocities with same mass)
momentum before = 20 * m - 20 * m = 0 = momentum after
I think that is what PsyDAG is assuming
