Observer S detects two flashes of light. A big flash occurs at x, = 1390 m and, 5.13 us later, a small flash occurs at x, = 780 m. As detected by observer S', the two flashes occur at a single coordinate x'. (a) What is the speed parameter of S', and (b) is S' moving in the positive or negative direction of the x axis? To S', (c) which flash occurs first and (d) what is the time interval between the flashes? (a) Number 0.397 Units This answer has no units (b) negativev (c) big v Units (d) Number
