A space elevator has an altitude above the Earth's surface of 40,000 km. What would be the kinetic energy of a 1kg mass at the end of our space elevator? What would be the gravitational potential energy of that mass? If the 1 kg object fell all the way down to the Earth's surface, what would be its speed just before impact? (The radius of Earth is 6.4 x 106 m).
