Answer:

A kiddie roller coaster car has a mass 100 kilograms. At the top of a hill, it’s moving at a speed of 3 meters/second. After reaching the bottom of the hill, its speed doubles. The car’s kinetic energy at the bottom is quadruple its kinetic energy at the top. The car has 1,800 joules of kinetic energy at the bottom of the hill.
