The Tunguska asteroid is estimated to have had a diameter of 50 m, and to have produced an explosion equivalent to 10 megatons of TNT (1 megaton = 4.2 x 1015 joules). Assume that the asteroid was a sphere with density 2 g/cm3. Using the kinetic energy formula K = ½ mv2, where m is the mass and v is the speed, to estimate the speed of the asteroid. Assume that all kinetic energy is converted into the energy of the explosion.
Give your answer in km/s with one significant figure.
Assume that a 10-km asteroid hits the earth at about 20 km/s
Computer simulations suggest that for large-energy impacts similar to the one described, water having about 3 times the mass of the asteroid is essentially instantly vaporized in an ocean impact.
What fraction of the asteroid’s energy does the energy required to do this represent?
About ___% of the asteroid’s energy is required to instantly vaporize water 3 times the mass of the asteroid.

Group of answer choices Short-period comets originate in the Kuiper belt and take less than than about 200 years to orbit the Sun. Long-period comets originate in the Oort cloud and can take millions of years to orbit around the Sun, in randomly oriented orbital planes. The ion tail of a comet tends to produce a blue glow, as the ions inside it absorb sunlight and re-emit the absorbed energy with a characteristic color (somewhat like the gas atoms in a neon light or in an Aurora). An ion tail is typically narrow and straight and always trails the comet, like long hair in the wind. The dust tail of a comet often looks curved and its whitish color is just reflected sunlight.arrow_forward
