Reference frame S' moves uniformly to the right and has its origin at the same point as S at t = t' = 0. Both flashes are observed to occur at the same place in S'. (a) Find the relative speed between S and S'. m/s (b) Find the location of the two flashes in frame S'. x' = m (c) At what time does the red flash occur in the S' frame? t = Need Help?

Tutorial Exercise A rocket moves with a velocity of 0.805c to the right with respect to a stationary observer A. An observer B moving relative to observer A finds that the rocket is moving with a velocity of 0.931c to the left. What is the velocity of observer B relative to observer A? (Hint: Consider observer B's velocity in the frame of reference of the rocket.) Click here to begin! Need Help? Read It Submit
