## Homework Statement

As measured by an observer on earth, a spacecraft runway has a length of 3.6km. What is the length of the runway as measured by the pilot of a spacecraft flying directly over the runway at a speed 4.00 x10^7 m/s relative to the earth?

## Homework Equations

L= Lnot/γ

## The Attempt at a Solution

I inserted 3.6km as the Lnot and got 3351m as the answer by using the equation.

L= 3600/ (1/sqrt(1-4.0E7/3.0E8))

= 3351m

Is this true? Or i have confused the L as Lnot? I got the answer as i figure the pilot is in rest and the runway is moving relative to him.
