Homework Statement
A satellite of mass 600kg is in a circular orbit about the Earth at a height above the Earth equal to the Earth's mean radius. Find:
a) the satellite's orbital speed
b) the period of its revolution
c) graviational force acting on it
Homework Equations
a) v^2 = GM/r
b) T = (2pie) r/ v
c) F = GmM/r^2
The Attempt at a Solution
for part a, is the satellites orbital speed dependent on the mass of the earth? Do I use mass of earth? or the satellite?
