help on two part question A). If a satelite with a mass of 12 x 10^2 kg is placed in an orbit around a planet with a mass of 2 x 10^20 kg, at a the distance of 117000 m from the center of the planet, find the speed the satelitle needs to be moving to stay in orbit. B).If a satelite with a mass of 9 x 10^2 kg is placed in an orbit around a planet with a mass of 4 x 10^20 kg, at a speed of 14000 m/s, find the distance from the center of the planet to the satelite.
