SUMMARY
The kinetic energy of an 840 Kg roller coaster trolley at the top of the second hill, which is 64.0 m above the ground, can be calculated using the principles of conservation of energy. Initially, the trolley has a speed of 0.200 m/s at the height of 85.0 m. By applying the conservation of mechanical energy, the potential energy at the first hill is converted into kinetic energy and potential energy at the second hill. The correct calculation yields a kinetic energy of 2,520 Joules at the top of the second hill.
