Question:

A satellite of mass $m$ is put into an elliptical orbit around the earth. At point $A$, its distance from the earth is $h_{1}=500 \mathrm{~km}$ and it has a velocity $v_{1}=30000 \mathrm{~km} / \mathrm{h}$. Determine the velocity $v_{2}$ of the satellite as it reaches point $B$, a distance $h_{2}=1200 \mathrm{~km}$ from the earth.
