1. The problem statement, all variables and given/known data
A clock is moving past us at speed $$v=\frac{c}{2}$$ reads $$t^{'}=0$$ when our clock read t=0. Using the Lorentz tranformation, find out what our clock will read when the moving clock reads 10s.

2. Relevant equations
$$t=\gamma(x^{'}+\frac{Vt^{'}}{c^{2}})$$

3. The attempt at a solution
Alright so I know I have this one wrong if I use the equation for time dilation I get 11.5 seconds and it is correct, but I am having trouble using the lorenz transformation to get the same answer. For $$x^{'}$$ I am using the equation Vt=x and get 5cs (light seconds), but I am ending up with a t=14. seconds.
I have some small silly disconnect somewhere. Help?

our clocks will read 0. What does the question really say?

that s wasnt real sorry and fixed the rest of the problem should be a little better now
