I'm sure it's a stupid question but this is my first crack at SR so help would be great.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

FrameS'has a speed of 0.7c along thexaxis relative to frameS. Clocks are adjusted sot=t'=0atx=x'=0.

An even occurs inSatt1 =3 x 10^7s atx1= 40m. At what time does the event occur inS'?

2. Relevant equations

[tex]\beta = 0.7[/tex]

[tex]\gamma = 1.4003[/tex]

[tex]x' = \gamma (x - t\beta c)[/tex]

3. The attempt at a solution

[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?
