Answer:
392,000 J
Explanation:
The formula to calculate the potential energy is:
PE = mgh
Where,
PE is the gravitational potential energy
m is the mass of the object
g is the acceleration due to gravity (9.8 m/s²)
h is the height of the object.
we have,
Mass of the roller coaster = 1000 kg
Height = 40 m
To solve for potential energy, substitute the required values in the above formula:
PE = 1000 × 9.8 × 40
PE = 4000 × 9.8
PE = 392,000 J
Therefore, the required potential energy is 392,000 Joules.
