Homework Statement
If a passenger at the back of a spaceship traveling at 3/5c fires a photon forward how long will it take to hit the front of the spaceship in the reference frame of the spaceship if it is 1 light second long? How long will it take in the stationary frame?
Homework Equations
T=t/(1-v^2/c^2)^1/2
The Attempt at a Solution
I completed the first half of the problem. Plugging in 1 second in for t (time it takes a photon to travel one light second) and 3/5c (the velocity of the reference frame) for v gives me 5/4 seconds. I just can't figure out what I should be inputting for the variables in the statuary reference frame. The answer sheet says a stationary observer would measure the time T to be 5/2 seconds.
