    Position of the front of an asteroid using special relativity

    (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...

    Position of the front of an asteroid using special relativity

    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...

    Integrating with respect to area? Past paper question

    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.

    Integrating with respect to area? Past paper question

    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...
