Relativistic reversal of events. Figures 37-25a and b show the (usual) situation in which a primed reference frame passes an unprimed reference frame, in the common positive direction of the x and x' axes, at a constant relative velocity of magnitude v. We are at rest in the unprimed frame; Bullwinkle, an astute student of relativity in spite of his cartoon upbringing, is at rest in the primed frame.The figures also indicate events A and B that occur at the following spacetime coordinates as measured in our unprimed frame and in Bullwinkle's primed frame:
In our frame, event A occurs before event B, with temporal separation ?t = tB - tA = 0.7 ?s and spatial separation ?x = xB - xA = 442 m. Let ?t' be the temporal separation of the events according to Bullwinkle. (a) At what value of ? is ?t' = 0? For what range of ? is the sequence of events A and B according to Bullwinkle the same as ours (b) - (c) and (d) - (e) the reverse of ours?
