A meteorite is 75,000 km from the center of Earth and falls to the surface of Earth. From Newton's law of gravity (see page 500), the force of gravity varies inversely as the square of the distance between the meteorite and the center of Earth. Find the work done by gravity if the meteorite weighs 160 N at the surface, and the radius of Earth is 6400 km.
