A relatively small impact crater 20 kilometers in diameter could be made by a comet about 2 kilometers in diameter traveling at 32 km/skm/s (32,000 m/sm/s).

Part A=Assume that the comet has a total mass of 3.6×1012 kilograms. What is its total kinetic energy? (Hint: The kinetic energy is equal to 1/2mv^2 where mm is the comet's mass and v is its speed.)

Part B=Convert your answer from part A to an equivalent in megatons of TNT, the unit used for nuclear bombs. (Hint: One megaton of TNT releases 4.2×10^15 joules of energy.)
