Relativity Calculation: Two bodies traveling at relativistic speeds

[QUOTE="PeterDonis, post: 6824672, member: 197831"] Where is earth in your scenario? Is it point A? Point B? Somewhere in between? ##48 / .82 = 58.54##, so this looks ok (although I would round up to 59 years if we are working to the nearest year). Gamma factor is ##1 / \sqrt{1 - .82^2} = 1.747##, and ##58.54 / 1.747 = 33.51##, so again this looks ok (although again I would round up to 34 years if we are working to the nearest year). Yes, since the speed of Body 2 is close enough to ##1## for this purpose. Not sure about this. I get a gamma factor of ##1000## for Body 2, which would mean travel time for the on board observer of ##48 / 1000 = 0.048## years, which works out to ##17.53## days. Will the light arrive at Body 1 before or after Body 1 reaches Point B? (I'm assuming both bodies stop when they reach Point B.) Answering that should make it much easier to answer this question. What time in the Point A/B (earth) rest frame does Body 2 arrive at Point B? Answering that should make it much easier to answer this question. [/QUOTE]
