A 52kg person walks from the ground to the roof of 78.52m tall building. How much gravitational potential energy is there?​USE GRESA METHOD

Respuesta :

Answer:

P = 40013.792 J

Step-by-step explanation:

Given that,

Mass of a person, m = 52 kg

The height of the building, h = 78.52 m

We need to find the gravitational potential energy at this point. It is given by the formula as follows :

P = mgh

Where g is acceleration due to gravity

P = 52 kg × 9.8 m/s² × 78.52 m

P = 40013.792 J

So, the gravitational potential energy is 40013.792 J.
