I'm sure it's a stupid question but this is my first crack at SR so help would be great.
Frame S' has a speed of 0.7c along the x axis relative to frame S. Clocks are adjusted so t=t'=0 at x=x'=0.
An even occurs in S at t1 = 3 x 10^7s at x1 = 40m. At what time does the event occur in S'?
[tex]\beta = 0.7[/tex]
[tex]\gamma = 1.4003[/tex]
[tex]x' = \gamma (x - t\beta c)[/tex]
[tex]x' = \gamma (x - t\beta c) = (1.4003)(40 - (3 * 10^7)0.7 c) = -32.21m[/tex]
Is this answer correct? It seems to me it can't possibly be right! What am I doing wrong?
