## Homework Statement

[Broken]

Answer is D.

[Broken]

Answer is E.

## Homework Equations

14. v=√(Gm/r)

17. p=mv

τ=rxF

L=Iω

## The Attempt at a Solution

Number 14 made perfect sense until I saw the answer, which is D. If the velocity of the spacecraft increases, according to v=√(Gm/r), the radius of the orbit decreases. So, I chose A. Why would the answer be D, where the earth becomes the focus of an elliptical orbit?

Number 17 also puzzles me. I thought that the answer was A, because the linear momentum decreases from its original value, while angular momentum is increased from 0 to a larger value. Why then, is the answer that linear momentum and angular momentum are both conserved?

Thanks in advance!
