The radius of the satellite’s orbit around the center of the Earth is r = 17 2 R , where R is the radius of the Earth. Hint: You may find it useful to take into account that the gravitational force is a conservative force. Hint: The universal gravitational force law is F~ = G M m r 2 ˆr . Earth R Satellite 17 2 R Caution: Neglect the rotational kinetic energy due to the Earth’s rotation. Find the energy required to launch a satellite from Earth into the circular orbit at the specified radius r = 17 2 R.
