A 1500 kg rollercoaster starts at the top of a frictionless hill with 200,000 J of gravitational potential energy and 50,000 J of kinetic energy. As the rollercoaster reaches the bottom of the hill, it now has 220,000 J of kinetic energy. Calculate the gravitational potential energy of the rollercoaster at the bottom of the hill.
