If two cars collide going 50 meters/ second head on. Their velocity final was 20 meters per second. For 10 meters. Could i find the momentum????

I don't think you can but there's a lot that I don't know. It's easy to find the ratio of the masses though; maybe you can see a way to apply that and find the answer you are looking for.

conserve momentum:
before = after
50m1 - 50m2 = 20(m1 + m2)
50m1 - 50m2 = 20m1 + 20m2
30m1 = 70m2
m1 = (7/3)m2
