3. The Moon orbits the Earth every 27.3 days with a near circular orbit of 385,000 km. What is the mass of the Earth based on this information? What is the kinetic energy of the moon? (mass of the Moon = 7.35 x 1022 kg) What is the potential energy of the moon? What is the acceleration due to gravity (towards the Earth) at the distance of the Moon?
