Scientists use models to help explain an idea, visualize hypotheses, and closely examine something (such as an atom).
The kinetic energy of an object is given by:

where
K is the kinetic energy
m is the mass of the object
v is its velocity.
The comet in our problem has a mass of

and a velocity of

, so its kinetic energy is:
