Homework Help: Relative speed and Time dilation

  1. Feb 4, 2009 #1
    1. The problem statement, all variables and given/known data
    What is the relative speed if two observers record a time difference of 1%


    2. Relevant equations
    t=(gamma)t'


    3. The attempt at a solution

    I use the above equation and solved for v, and got

    v=sqrt(-c2((t'/t)2-1)

    however I am gettin 2.999x108m/s, and I am pretty sure that is not right.

    Perhaps you can relate [itex] \frac{t}{t'} [/itex] to the 1% time difference. If you can do this you could find a velocity by solving [itex] \frac{t}{t'} = \gamma [/itex] for the v in gamma.
