Answer:
The airplane gravitational potential energy is 78.4 MJ.
Step-by-step explanation:
Given:
Mass of airplane, m = 40000 kg
Height above ground , h = 200 m
To Find:
Gravitational Potential Energy = ?
Solution:
Gravitational Potential Energy :
Gravitational potential energy is energy an object possesses because of its position in a gravitational field.
Formula is given by

Where,
m = mass
g = acceleration due to gravity = 9.8 m/s²
h = height
Substituting the values we get

The airplane gravitational potential energy is 78.4 MJ.
