Question
A roller-coaster car is at the top of a hill. The car and its passengers have a combined mass of 1,088 kilograms. If the hill is 62 meters tall, how much potential energy does the car have? PE=mgh (1 point) Responses 330,534.4 J 330,534.4 J 1,159.8 J 1,159.8 J 67,456 J 67,456 J 661,068.8 J
Answers
GPT 3.5
PE = mgh
PE = 1088 kg * 9.8 m/s^2 * 62 m
PE = 1088 kg * 9.8 m/s^2 * 62 m
PE = 1088 kg * 607.6 m^2/s^2
PE = 661,068.8 J
Therefore, the roller-coaster car has 661,068.8 Joules of potential energy.
Correct answer: 661,068.8 J
PE = 1088 kg * 9.8 m/s^2 * 62 m
PE = 1088 kg * 9.8 m/s^2 * 62 m
PE = 1088 kg * 607.6 m^2/s^2
PE = 661,068.8 J
Therefore, the roller-coaster car has 661,068.8 Joules of potential energy.
Correct answer: 661,068.8 J
