Question

If a 2x1014 kg comet impacts the ocean at a speed of 10 km/s, and 1% of the comet's impact kinetic energy goes to boiling the water (the other 99% is going to produce waves in the water), what mass of water will be boiled during the impact? Consider the initial temperature of the water to be 10oC, and that the specific heat of the sea water is the same as fresh water, 4.184 J/gK, as well as the heat of vaporization, 2260 J/gK. For comparison, the mass of the Earth's oceans is considered to be on the order of 1021 kg.
