A) When a falling meteoroid is at a distance above the Earth's surface of 2.90 times the Earth's radius, what is its acceleration due to the Earth's gravitation?

m/s2 towards earth

B) The free-fall acceleration on the surface of Neptune is about one and one half times that on the surface of the Earth. The radius of Neptune is about 3.50 RE (RE = Earth's radius = 6.4 106 m). Find the ratio of their average densities?

Neptune/Earth

C) An artificial satellite circles the Earth in a circular orbit at a location where the acceleration due to gravity is 7.71 m/s2. Determine the orbital period of the satellite.
