Relativity, reference frames and Lorentz transformations

  1. Aug 22, 2010 #1
    1. The problem statement, all variables and given/known data

    The system [tex]S'[/tex] moves in relation to the system [tex]S[/tex] with velocity [tex]\upsilon[/tex] along the -[tex]x[/tex]- axis. At the time when the beginnings of the coordinate system are in the same point, clocks in both system shows [tex]t=t'=0[/tex]. Which coordinates will have a reference point during the motion in every of these systems, which has the property that in some next moment clocks in systems [tex]S[/tex], [tex]S'[/tex] shows the same time [tex]t=t'[/tex]. Determine the law of motion of motion of this point.

    2. Relevant equations
    Lorentz transformation

    [tex]x'=\frac{x-\upsilon t}{\sqrt{1-\frac{{\upsilon}^2}{c^2}}}[/tex]




    3. The attempt at a solution

    I tried like this







    and get

    [tex]x=\frac{\upsilon t}{\sqrt{1-\frac{\upsilon^2}{c^2}}+1}[/tex]

    Is this correct?
