According to the calculator at https://www.calculatorsoup.com/calculators/physics/kinetic.p... , 1 gram traveling at 29,979,245.8 m/s has 449,377,589,368.41 J, or about 449 gigajoules. According to a quick search, the asteroid that killed the dinosaurs had about 300 zettajoules of energy. 1 zettajoule is 1,000,000,000,000 gigajoules. So it would be on the order of a trillionth as much energy as the Chicxulub impact. |
