Physics Relativity Question?
A rocket ship is moving directly toward Earth with a constant speed of 0.50 c relative to Earth. It turns on its headlight, and the light beam travels toward Earth with speed c relative to the ship. According to the rocketship astronauts, Earth is 6.00 x 10^12 m away when the headlight is turned on. In the frame of the astronauts, how long does it take for the light to reach Earth? (Hint: in the frame of the astronauts, Earth is approaching the ship with a speed of 0.5c)
c = 3x10^8 m/s
I just got 20000 seconds but i know its wrong
