In a particular inertial reference frame, two events along the x-axis are observed/determined to occur 30 seconds apart temporally with the second event occurring after the first, and 34 light- seconds apart spatially with the spatial coordinate of the second being larger than the first. a) Above what minimum speed (as a fraction of c) would a second inertial observer need to travel along the first's positive x-axis so that the second event would be determined to occur before the first? [Enter the exact speed, or 0 if you deem this to be not possible.] v> b) Suppose that an inertial observer travels exactly at the critical speed you found in part a), so that the events are deemed to be simultaneous (instead of in the opposite order). What is the exact spatial interval between the two events in this frame (with the same event 'labelling')? [If you concluded part a) was not possible, enter 0 here.] C-S
