Question

Revolt · Accepted Answer

2,000; If a roller coaster train has a potential energy of 1,500 J and a kinetic energy of 500 J as it starts to travel downhill, its total energy isJ.: 2,000; Once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 J, and its potential energy decreases to J.: 900; When the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isJ.: 2,000
