    2. Relevant equations

    3. The attempt at a solution

    I don't know if I did this right. If I did, I can't find what meaning the inverse of this functions has :S. Any help is appreciated.

    f is a map from v to m, ie
    m = f(v)

    f-1 will be the map from m to v, ie
    v = f-1(m)

    I think I understand this, but what does it mean physically speaking in terms of mass and the velocity?

    not too sure... maybe that for a given object there is one to one correspondence between mass & magnitude of velocity, so f-1, is the unique map from mass to velocity magnitude
