Yeah in 5, in the rocket frame the signal just travelled the distance of the rocket (because the speed of light is constant in all reference frames). But in the frame of the space station I think I got it travelled 200m. And yeah, I'm actually glad I didn't really study. Although I tried 6 and got some disgusting equation in the end, but it was only in terms of v and c and constants, so it might be right. I really didn't use the energy-momentum invariant as much as I thought I would.
And yeah...I didn't really look past 5a, cause I was slightly confused. But 6 was math heavy and yeah, it took a while to factor a single v out, but I got it in the end. My answer was negative, but that just depends on which object you're solving for, since the asteroid and rocket were traveling in opposite directions.
If I don't get 100% on that midterm I'll be really surprised.
