Find the gpe of 40,000 kg airplane moving at 80 m/s at 200 meter above the ground.

The airplane gravitational potential energy is 78.4 MJ.

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.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
