A rocket ship is 45.0 m long according to measurements made in its rest frame, and moves at 0.385c by respect to the Earth. Astronaut Naomi sends a laser pulse from the tail of the rocket to the nose, where it reflects off a mirror, and returns to Naomi. (a) How long does the round trip take, according to Naomi? (b) How long does the round trip take according to Tariq, an observer on Earth?
