Two events A and B occur on the x- axis of S frame. Event A occurs at (x1=1000m, ti=0) and B occurs near the observer 3.0 s later. (x2=0, t2-3.0 us). Find the speed (u) and the direction of motion of frame S' such that these two events seem to occur simultaneously in that frame. (Note that in the figure direction of u is arbitrarily drawn to the right). In this case, how far apart are these two events as seen by an observer in S'? y' S' u S Y B(x2=0, t2=3us) X A(x1-1000m, t-0)
