Homework Statement
Answer is D.
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!
