## Homework Equations

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

[itex]L_{0}=\gamma L[/itex]

[itex]\delta T=\gamma\delta T_{0}[/itex]

## The Attempt at a Solution

I think that [itex]\frac{L_{A}}{\gamma}=L_{C}[/itex] but this is where I'm stuck... how do I find the time using what little i have?
