A red light flashes at position xR = 3.00 m and time tR = 1.00 x 10-9 s, and a blue light flashes at xB = 5.00 m and tB = 9.00 x 10-9 s, all measured in the S reference frame. Reference frame S" has its origin at the same point as S at t = t = 0; frame S" moves uniformly to the right. Both flashes are observed to occur at the same place in S".
(a) Find the relative speed between S and S".
(b) Find the location of the two flashes in frame S".
(c) At what time does the red flash occur in the S" frame?
