1. An observer in a rocket moves toward a mirror at a speed 0.6 c relative to the reference frame labeled by S in the figure. The mirror is stationary with respect to S. A light pulse emitted by the rocket travels toward the mirror and is reflected back to the rocket. The front of the rocket is a distance 1.88 10 ^12 m from the mirror (as measured by observers in S) at the moment the light pulse leaves the rocket. Mirror v = 0.6 c.
What is the total travel time of the pulse as measured by observers in the S frame? Answer in units of s.
2. What is the total travel time of the pulse as measured by observers in front of the rocket? Answer in units of s
