Relativistic speeds going perpendicular

  1. Feb 4, 2012 #1
    Couldnt find anything from 15min of forum searching...

    If 2 objects are travelling along say, an x and y axis(or just 90 degrees apart really) at close to c, how do they interpret each others speeds? 0<theta<90 are easy enough. Couldnt find anything about perpendicular though.

    A newtonian version of this problem is simple enough but I am not sure when you are going at the speeds I am tlaking about.

    They're just going to interpret the other one as moving directly away at slightly closer to c.
