Space cruisers A and B are moving parallel to the positive direction of an x axis. Cruiser A is faster, with a relative speed of v = 0.871c, and has a proper length of L = 287 m. According to the pilot of A, at the instant (t = 0) the tails of the cruisers are aligned, the noses are also. According to the pilot of B, how much later are the noses aligned? Number i Units Current Attempt in Progress Reference frame S' passes reference frame S with a certain velocity. Events 1 and 2 are to have a certain temporal separation At' according to the S' observer. However, their spatial separation Ax' according to that observer has not been set yet. The figure below gives their temporal separation At according to the S observer as a function of Ax' for a range of Ax' values. The vertical axis scale is set by At 6.00 s. What is At' in case Ax'=0?
