(Solved) : Consider Comet 2 Kilometers Across Mass 4 X 10 12 Kg Assume Crashes Earth Speed 3 X 10 4 M Q32942059 . . .
Consider a comet about 2 kilometers across with a mass of 4 x10^12 kg. Assume that it crashes into Earth at a speed of 3 x 10^4m/s.
a.) What is the total energy of the impact, in joules? (Hint:The “kinetic energy” formula tells us that the impact energy injoules will be 1/2mv^2 where m is the comet’s mass inkilograms and v is its speed in meters per second.)
b.) A 1-megaton nuclear explosion releases about 4 x 10^15 joulesof energy. By comparing your answer with the energy released from anuclear explosion, comment on the degree of devastation the cometmight cause.
