AFTER the collision, there is no momentum.
Momentum before = momentum after if there is no net force on system
(Newton ONE)
(Newton ONE)
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
