Yeah for r1 I did the radius of the planet plus the radius of the satellite.
So it should be 5700 kg up in orbit and still 5700 kg on the planets surface? Edit: I guess the answer is supposed to be in "N"
Homework Statement
A satellite has a mass of 5700 kg and is in a circular orbit 4.2 multiplied by 10^5 m above the surface of a planet. The period of the orbit is two hours. The radius of the planet is 4.25 multiplied by 10^6 m. What is the true weight of the satellite when it is at rest on...
