Satellite in orbit
A satellite has a weight of 10^4 N at ground control. The satellite will be sent out to space at a distance of twice the radius of the earth. What is the acceleration of the satellite once in orbit?

the local gravitational constant g is the gravitational acceleration. It is found by
g =GM/r^2. At the surface of earth, it's value is 9.81 m/s/s. At twice the radius of earth, you can see that it should be 1/4 the acceleration, so 2.45 m/s/s
