A 59.31 kg rock is sitting at the top of a cliff that is 300 m tall. What is the gravitational potential energy of that rock?

Respuesta :

Answer:

The gravitational potential energy of that rock is 174371.4 J.

Explanation:

Given

  • Mass m = 59.31 kg
  • Height h = 300 m

To determine

We need to find the gravitational potential energy of the rock

We know that the potential energy of a body is termed as the stored energy due to its position.

One kind of energy comes from Earth's gravity — Gravitational potential energy (GPE).

Gravitational potential energy (GPE) can be determined using the formula

[tex]GPE = mgh[/tex]

where

  • [tex]m[/tex] is the mass
  • [tex]g[/tex] is the gravitational acceleration which is equal to g = 9.8 m/s²
  • [tex]h[/tex] is the height
  • GPE is the Gravitational potential energy

now substituting m = 59.31, h = 300 and g = 9.8

[tex]GPE = mgh[/tex]

         [tex]=59.31\times 9.8\times 300[/tex]

         [tex]=174371.4[/tex] J

Therefore, the gravitational potential energy of that rock is 174371.4 J.
