Isn't the speed at which one of the objects is moving away from the other 24c/25 per the relativistic velocity addition formula?

- walnutclosefarm 5y agoIt's quite possible to have the apparent rate of separation of two particles, from the standpoint of third frame of reference, be superluminal. It happens in astronomical observations. See http://spiff.rit.edu/classes/phys200/lectures/superlum/superlum.html http://spiff.rit.edu/classes/phys200/lectures/superlum/super... for a nice example and explanation. But you are quite right that from the frame of reference of either of the two particles sent traveling at .75c in opposite directions, the other particle is receding at subluminal velocity, not FTL.
