Problems are listed in approximate order of difficulty. A single dot (•) indicates straightforward problems involving just one main concept and sometimes requiring no more than substitution of numbers in the appropriate formula. Two dots (••) identify problems that are slightly more challenging and usually involve more than one concept. Three dots (•••) indicate problems that are distinctly more challenging, either because they are intrinsically difficult or involve lengthy calculations. Needless to say, these distinctions are hard to draw and are only approximate.
•• The frames S and S′ are in the standard configuration with relative velocity 0.8c along Ox. (a) What are the coordinates (x1,y1, z1, t1) in S of an event that occurs on the x′ axis with x′1 = 1500 m, t′1 = 5 μs? (b) Answer the same for a second event on the x′ axis with x′2 = −1500 m, t′2 = 10 μs. (c) What are the time intervals (Δt and Δt′) between the two events, as measured in S and S′?
