Homework Statement
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.
Homework Equations
Vesc = Sq.root of 2GMp/r
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.
