An 884 kg satellite in orbit around a planet has a gravitational potential energy of -5.44*10^10 J.

The orbital radius of the satellite is 8.52*10^6 m and its speed is 7.84*10^3 m/s.

A) What is the mass of the planet?

B) What is the kinetic energy of the satellite?

C) What is the total energy of the satellite.

Thank you.
