A meteorite with a mass of 25 kilograms falls to Earth in a direction perpendicular to the Earthís surface. At t = 0 seconds the meteorite is 1000 meters above the Earth. At
t = 2 seconds it is 750 meters above the Earth. Assume the meteoriteís acceleration
due to gravity is constant during this time. Which of the following is the amount of
work the Earthís gravitational force has done on the meteorite between t O and t =
2?
