The Chelyabinsk meteor was about 20 meters across. To make your work easier, assume that the object was spherical so its diameter was 20 meters. Further, assume that the asteroid has a typical density of about 2 grams per cubic centimeter (so about 2,000 kilograms per cubic meter). Based on the asteroid's orbital motion, its speed was about 17 kilometers per second before it entered Earth's atmosphere. How much kinetic energy did the Chelyabinsk asteroid have before entering Earth's atmosphere?...
