The plane of clocks and measuring rods in Fig. 37-19 is like that in Fig. 37-3. The clocks along the x axis are separated (center to center) by 1 light-second, as are the clocks along the y axis, and all the clocks are synchronized via the procedure described in Module 37-1. When the initial synchronizing signal of t = 0 from the origin reaches (a) clock A, (b) clock B, and (c) clock C , what initial time is then set on those clocks? An event occurs at clock A when it reads 10 s. (d) How long does the signal of that event take to travel to an observer stationed at the origin? (e) What time does that observer assign to the event?

The proper mean lifetime of a muon is 2.2 × 10–6 s. A beam of muons is moving with speed 0.6c relative to an inertial observer. Approximately how far will a muon in the beam travel, on average, before it decays?
Spatial separation between two events. For the passing reference frames of the figure, events A and B occur with the following spacetime coordinates: according to the unprimed frame, (xA, tA) and (xB, tB); according to the primed frame, (x'A, t'A) and (x'B, t'B) . In the unprimed frame, Δt = tB - tA = 2 μs and Δx = xB - xA = 497 m. At what value of β is Δx' minimum?
At the instant that a clock standing next to you reads t = 1.0 μs, you look at a second clock, 300 m away, and see that it reads t = 0 μs. Are the two clocks synchronized? If not, which one is ahead?
