The gravitational potential energy of Sara at the given height is 10594.8J.

Given the data in the question;

  • Mass of Sara; m; = 60kg
  • Distance from ground; h = 18m
  • Acceleration due to gravity; g = 9.81m/s^2
  • Gravitational potential energy; U = \ ?

<h3>Gravitational Potential Energy</h3>

Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.

It is expressed as;

U = mgh

Where m is mass, h is height and g is acceleration due to gravity.

To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.

U = mgh\\\\U = 60kg * 9.81m/s^2 * 18m\\\\U = 10594.8kgm^2/s^2\\\\U = 10594.8J

Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.
