Complete these sentences. 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. 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. When the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isJ.

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. When the train reaches the bottom of the track and is traveling along the ground, its kinetic energy is J.

The answer is: 2000 J for the first sentence, 900 for the second sentence, and 2,000 for the last one
