Homework Help: Space and time events

  1. Oct 13, 2006 #1
    hi, wondering if anyone could give me a little help with this question

    The space and time coordinates of two events are measured in frame S to be:

    Event 1: x1 = L, t1 = L/c

    Event 2: x2 = 2L, t2 = L/2c

    (a) find the velocity of a frame S' in which both events occur at the same time?

    (b) What is the time t' that both events occur in S'?

    Write t_1'=gamma(t_1-vx_1/c^2), and equate that to the same equation for
    t_2'. Then, solve for v.
