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.
