An S observer living on the x-axis observes a flash of red light (V) at x=1210m and after 4.96 μs, records a blue light pulse (A) at x=480m. Tip: To better organize your answer, use the V and A subscripts to label the coordinates of events. (a) What is the velocity with respect to S of an observer S' that records events as occurring in the same position? (b) Which event occurs first for S'? (c) What is the time interval measured by S' between events?
