Where on a roller coaster is there equal amounts of potential energy and kinetic energy?

At the top of the hill, the roller coaster car has the most potential energy because it is at its highest point. It also has the least kinetic energy because it is moving the slowest. As the car goes down the hill, its potential energy decreases and its kinetic energy increases. At the bottom of the hill, the car has the least potential energy and the most kinetic energy.
