An event has spacetime coordinates (x, t) = (1200 m, 3.0 μs) in reference frame S.
What is the event's spacetime coordinate x' in reference frame S' that moves in the positive x-direction at 0.80 c?
What is the event's spacetime coordinate t' in reference frame S'?
What is the event's spacetime coordinate x'' in reference frame S'' that moves in the negative x-direction at 0.80 c?
What is the event's spacetime coordinate t'' in reference frame S''?
