## Homework Statement

At x = x' = 0 and t = t' = 0, a clock ticks on a fast spaceship (gamma = 100). The captain of the ship heads it tick again 1.0 s later. Where and when do we (the stationary observers) measure the second tick to occur?

## Homework Equations

[tex]t = \frac{t'}{\gamma}[/tex]

[tex]x' = \gamma(x - vt)[/tex]

[tex]\gamma = \frac{1}{\sqrt{1 - \frac{v^2}{c^2}}}[/tex]

## The Attempt at a Solution

First, I solve for velocity.

[tex]v = c\sqrt{1 - \frac{1}{100}^2} = 0.9995c[/tex]

Next, solve for t when t' = 1.

[tex]t = \frac{t'}{\gamma} = \frac{1}{100} sec[/tex]

Finally, solve for x'.

[tex]x' = \gamma(x - vt) = 100(0 - (0.9995c)(\frac{1}{100})) = 0.9995c [/tex]

Have I answered this correctly? Thanks.
