Consider the astronaut planning the trip to Andromeda in 71. (a) To three significant figures, what is the value for g for the speed found in part (a) of 71? (b) Just as the astronaut leaves on his constant-speed trip, a light beam is also sent in the direction of Andromeda. According to the Earth observer, how much later does the astronaut arrive at Andromeda after the arrival of the light beam?
