A rocket speeds by the earth at 0.77c. The earthlings measure the moving rocket to be 158 m long. What is the length of the rocket as measured by the passengers on the rocket? Please give your answer in meters. As I speed by in my very fast train (v = 0.757c), I jump up. In my frame, it takes me 0.71 s to go up and come back down. How long does it take as measured by somebody standing next to the tracks? Please give your answer in seconds.
