1. The problem statement, all variables and given/known data [Broken] Answer is D. [Broken] Answer is E. 2. Relevant equations 14. v=√(Gm/r) 17. p=mv τ=rxF L=Iω 3. 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!
