western United States and western Canada, much like a stone skipped across water. The accompanying fireball was so bright that it could be seen in the daytime sky and was brighter than the usual meteorite trail. The meteroite's mass was about 4x106 kg; its speed was about 15 km/s. Had it entered the atmosphere vertically, it would have hit the Earth's surface with about the same speed. A) Calculate the meteorite's loss of kinetic energy (in joules) that would have been associated with the vertical impact. B) Express the energy as a multiple of the expolsive energy of 1 megaton of TNT, which is 4.2x 1015 J. C) The energy associated with the atomic bomb explosion over the Hiroshima was equivalent to 13 kilotons of TNT. To how many HIroshima bombs would the meterorite impact have been equivalent?
