What's the kinetic energy of the roller coaster at the top and bottom of the hill? Use. 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 its kinetic energy at the top. The car has ___ joules of kinetic energy at the bottom of the hill.
