The graph of mass versus kinetic energy shows that mass is proportional to kinetic energy. In other
words, as the mass of the car increases, its kinetic
energy increases at the same rate.

Consider two cars, with the second car having a
mass six times the mass of the first car. Compare
the kinetic energy of each car. Then describe the
implications of your answer for using brakes to
bring each car to a complete stop.
