I'm getting quite stuck on this problem here.
Galileo said that Xb = Xa - V*Ta.
(This follows from dv = dx/t --> Xa - Xb = t*dv --> the above formula)
Thus, it is concluded Xa = Xb + V*Ta, but why?
In my thought experiment the objects are moving relative to each other,
thus if A is moving away from B, then B is moving away from A.
(I also read that it is convention for the Doppler-effect that V is + for source and observer approaching each other and - for source and observer receding each other)
So should V not be positive or negative for both equations?
