In the S' system, Bob observes three e', f' and g' clocks, which move to v=[(3)^(1/2)]/2 and pass three stationary e, f and g clocks, which are synchronized in the S' system and the e, f and g clocks are synchronized in the S system. Just when the stationary clocks mark zero, the three moving clocks appear aligned with them, and Bob observes that f' also marks zero. A) How far apart are the clocks in motion in the system where they are at rest? Argument your answer B) Make two space-time diagrams, one from S and the other from S', which include the world lines of the clocks. Use them to argue your answers to the following paragraphs. C) What is the reading of e' in seconds when it coincides with e?
