A 200 m long rocketship moves parallel to its length with speed v = 0.9c relative to you. (a) Compute the length of the rocketship measured by you. (b) How long does it take for the rocketship to pass you? (c) In the frame-of-reference of the rocketship, how long does it take for you to travel from one end of the rocketship to the other as you pass by the rocketship? (d) One of the two time intervals calculated in (b) and (c) corresponds to a proper-time interval. Which one? Why?

Answer #1

a) The length of the rocket ship measured by the observer is, (0.9c) -87.177 m Therefore, the length of the rocket ship is |L

Time taken by the observer to travel from one end to another end is, AT 0.9c 200 0.9x3x10 7.41x10-s Therefore, the taken time
