The gravitational potential energy of the rock at the top of the cliff is 41895 Joules.

What is gravitational potential energy?

Gravitational potential energy is simply the potential energy an object possessse in relation to another object due to gravity.

It is expressed as;

U = mgh

Given the data in the question;

  • Mass m = 95kg
  • Height h = 45m
  • Acceleration due to gravity g = 9.8 m/s²

We substitute our values into the expression above.

U = mgh

U = 95kg × 9.8m/s² × 45m

U = 41895kgm²/s²

U = 41895J

Therefore, the gravitational potential energy of the rock at the top of the cliff is 41895 Joules.
