A satellite with a mass of 5.00x10^2 kg is in a circular orbit, whose radius is 2re, around Earth. Then it is moved to a circular orbit with a radius of 3re.

e) Calculate the escape velocity for the satellite if it is on Earths surface.

2. Relevant equations

Vesc = Sq.root of 2GMp/r

3. The attempt at a solution

Vesc = Sq.root of 2(6.67x10^-11)(5.98x10^24)/6.38x10^6

Vesc = Sq.root of 125036363.6

Vesc = 11182.966 m/s

Therefore the velocity of the satellite must be > 11182.966 m/s

I must of done something wrong because 11000m/s seems way to fast! Plz help.

Thanks in advance.
