Problem
A planet of mass 7.0×10^24 kg is orbited by a 550 kg satellite. Initially the satellite’s gravitational potential energy is −2.6×10^10 J. After a brief engine burn, its gravitational potential energy becomes −1.3×10^10 J. Calculate the increase in the satellite’s orbital radius (measured from the planet’s center). Give your answer in meters. Use G = 6.67×10^−11 N·m^2/kg^2.
