Question

A diver who has a mass of 68 kg climbs to a diving platform that is 7.5 m above the surface of a pool. How much gravitational potential energy does the diver have in relation to the pool’s surface?

Answer 1

The answer is 4998 J.

Answer 2

Answer: 4,998 J

Explanation:

The gravitational potential energy of an object is given by

$E_p=mgh$

where

m is the mass of the object

g is the gravitational acceleration

h is the heigth of the object with respect to a reference point

In this problem, m=68 kg, g=9.8 m/s^2, and h=7.5 m is the heigth of the diver with respect to the surface of the pool. Therefore, the gravitational potential energy of the diver with respect to the surface of the pool is

$E=mgh=(68 kg)(9.8 m/s^2)(7.5 m)=4,998 J$
