The radius of the satellite’s orbit around the center of the earth is r = 7 r , where r is the radius of the earth. 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 = 7 r. answer in units of j. 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[mm/r^2](r hat)
