Question

4/10

Answer 1

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; $U = \ ?$

Gravitational Potential Energy

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.
