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.

<h3>What is effects of solid wastes?</h3>

Solid wastes are those materials that are discarded from factories and facilities which may contain chemicals that are able to pollute the water bodies.

When they are being washed into the water body, they build up in the body of fishes in a process called bio magnification.

Bio magnification is a process whereby chemicals that are washed into the water bodies accumulate on the body of animals (wildlife) through eating of aquatic animals.

When animals feed on these fishes, it harms their health with time.

Therefore, Solid waste can harm wildlife by the mercury contained in fish builds up in animals that eat the fish.
