    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
