Homework Statement
A spaceship travels from Earth to a star that is 6 light years away. The spaceship takes 2.5 years to reach the star in its frame. Calculate the velocity of the spaceship.
Homework Equations
[itex]x=\frac{x_0}{γ}[/itex], [itex]t=γt_0[/itex]
The Attempt at a Solution
I guess I have to relate the two equations to work out velocity somehow. Previous attempts where I considered the distance, [itex]6ly[/itex] divided by the velocity of the spaceship was equal to the time it takes to travel to the star as seen on Earth. I then substituted [itex]t[/itex] for [itex]γt_0[/itex] where [itex]t_0=2.5y[/itex] and rearranged to find [itex]v[/itex], but this was unsuccessful. I don't have any other ideas to try so hints would be appreciated.
