At its tallest point a rollercoaster lifts participants to a height of 115 m. The combined mass of a fully loaded coaster train with participants that each weigh 100kg is a total of 4,500 kg. Calculate the gravitational potential energy of the coaster train and its riders relative to the ground using the formula U9= mgh. Assume the acceleration due to gravity on Earth g= 10 m/s/s.
