The mass of the Earth is 5.972kg, and the radius of Earth is 6, 371 km. A 750 kg satellite orbits 35, 800 km above Earth in a perfectly circular orbit.
1. If the gravitational force is the centripetal force keeping the satellite in a stable cicular orbit, how does the centripetal force compare to the gravitational force.
2. If the gravitational force is the centripetal force keeping the satellite in a stable circular orbit, what is the tangential velocity in (m.s) of the satellite's orbit.
3. How long (in hours) does this satellite take to orbit Earth?
