Question
In the best case scenario for a gravity boost, a
spacecraft approaches a planet very closely and
does a U-turn around it, heading back exactly in
the direction it came (see the image below).
Before Collision
V
After Collision
If the spacecraft was initially going to the right
with a speed of 5 km/s, and the planet was
going to the left at a speed of 9 km/s, what
would be the fastest the spacecraft could be
going after the U-turn, in km/s?
