A satellite of mass 6000 kg orbits the Earth in a circular orbit of radius of 9.0*10^6 m (this is above the Earth's atmosphere).The mass of the Earth is 6.0 * 10^24 kg.
(a) What is the magnitude of the gravitational force on the satellite due to the earth?
F= N
(b) Using the momentum principle, find the speed of the satellite in orbit.
v= m/s
(c) Using the energy principle, find the minimum amount of work needed to move the satellite from this orbit to a location very far away from the Earth.
work= J
