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
Given:
m = 1,088 kg
g = 9.8 m/s^2 (acceleration due to gravity)
h = 62 m
Potential energy (PE) = mgh
PE = 1,088 kg * 9.8 m/s^2 * 62 m
PE = 67,849.6 J
Therefore, the roller-coaster car has 67,849.6 Joules of potential energy at the top of the hill.
