A roller coaster car is at the top of a hill. The car and its passengers Have a combined mass of 1088 kilograms
To calculate the gravitational potential energy of the roller coaster car at the top of the hill, we need to know the height of the hill. Gravitational potential energy is given by the equation:
Potential Energy = mass * gravity * height
Where:
mass = 1088 kg (mass of car and passengers combined)
gravity = 9.8 m/s^2 (acceleration due to gravity)
Since the height is not provided in the question, it is not possible to calculate the gravitational potential energy.
