Apparently, it's some sort of HW problem or exam. Where's the rest of it?

To me, these questions seem self-explanatory. If you have a specific question about something which is unclear, I'll try to help. But simply saying 'Explain this' is too vague.

Well, what happens when you shoot something out of a gun? Study the details given in section (c) and ask yourself if it would be safe for a man inside the spacecraft to be shot out of a gun.

It takes a certain velocity to achieve orbit. By siting the gun on the equator, how does this help achieve that velocity? What does the earth do all day?
