Answer:

The gravitational potential energy of that rock is 174371.4 J.

Step-by-step 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


GPE = mgh

where


  • m is the mass

  • g is the gravitational acceleration which is equal to g = 9.8 m/s²

  • h is the height
  • GPE is the Gravitational potential energy

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


GPE = mgh


=59.31* 9.8* 300


=174371.4 J

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