About 65 million years ago an asteroid struck Earth in the area of the Yucatán Peninsula and wiped out the dinosaurs and many ot
her life forms. Judging from the size of the crater and the effects on Earth, the asteroid was about 10 km in diameter (assumed spherical) and probably had a density of 2.0 g/cm3 (typical of asteroids). Its speed was at least 11 km/s. 1) What is the maximum amount of ocean water (originally at 20∘ C) that the asteroid could have evaporated if all of its kinetic energy were transferred to the water? Express your answer in kilograms and treat the ocean as though it were freshwater. If the water were formed into a cube, how high would it be?
2)If the water were formed into a cube, how high would it be?
