## Homework Statement

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'*?

## Homework Equations

[tex]\beta = 0.7[/tex]

[tex]\gamma = 1.4003[/tex]

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

## 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?
