**Andrew**, Wednesday, May 9, 2012 at 10:04pmcalculate change in the momentum. remember that after it experiences this "perfectly elastic collision" it has a negative velocity. Therefore the change in momentum would be p = abs|m1v1 + m2v2|

change in momentum p = Ft

Force would be the average force or in this case the constant force
