Your job with NASA is to monitor satellite orbits. One day, during a routine survey,

you find that a 400 kg satellite is going to collide with a smaller 100 kg satellite travelling in the same

orbit but in the opposite direction. Knowing the construction of the two satellites you expect they will

become enmeshed into a single piece of space junk. When you notify your boss of the impending

collision, he asks you to quickly determine whether the space junk will continue to orbit or crash into

Earth.

my work so far....

**(Msat • v2) / R = (G • Msat • MCentral ) / R2**
Where Mcentral is Mearth

I'm completely lost after this... im not sure where im headed either, I would be eternally grateful if someone could outline what is needed here... thanks!
