Assume that the comet has a total mass of 4.2×1012 kilograms. what is its total kinetic energy? (hint: the kinetic energy is equal to 12mv2, where m is the comet's mass and v is its speed. if you use mass in kilograms and velocity in m/s, the answer for kinetic energy will have units of joules.)

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
