(Correction for original post: the speed is supposed to be ##\frac{\sqrt{3}}{2}c##, which then gives ##\gamma=2##.) Thanks, I can't believe how long I spent without noticing that. So, the time in ##F## is: $$t=\frac{D}{v}=\frac{8}{3}\sqrt{3}\mu s$$ Therefore the time in ##F'## is...

Homework Statement I'm stuck on part (d) but I've included the previous subquestions in case they're useful. The length of an asteroid is exactly 300 m = 1 µls (micro light-second) when at rest. Draw a carefully labelled space-time diagram to illustrate the following: (a) Depict the rest...

Zero :) I think I understand it now, I tried a double integral method earlier and it gave me zero and I thought that it was wrong, but after considering it properly I think that it's right.

This isn't exactly homework or coursework, it is a past paper question that I cannot find a solution to (my university doesn't like releasing answers for some reason unknown to me). The question is attached as an image (edit: the image displays while editing but not in the post, so I'll try to...
