An observer in frame S sees lightning simultaneously strike two points 120 m apart. The first strike occurs at 21 = 80 m, y1 = 21 = 1 = 0 and the second at 2 = -40 m, 12 = 22 = t2 = 0. (a) Find the coordinates of these two events in a frame S' moving in the usual configuration at 0.8c along the x-axis of S. (b) How far apart are the events in S'? (c) Find the difference in time between the events, as seen in S'. Which event occurs first in S
