g spaceship has a life support system that can keep its crew alive for 800 hours. The crew wants to travel a distance of 1x1015 m (as measured in the rest frame of the start and end points). es a pulse of light ~927 hrs to travel the same distance. Does this mean that the ship will have to travel faster than light? Explain why or why not. [1] b) How fast will the ship have to go so that it can travel 1x1015 m without depleting its life support system? Express your answer as a fraction of the speed of light. [4] Hint: 훾ଶ훽ଶ= ఉమଵିఉమ, where 훽= 푣/푐. c) How long did the trip take according to an observer at rest at the destination? [1]
