Question

A child with a mass of 25.0 kg is a the top of a slide in an amusement park. If the vertical

height of the slide is 4.00 m, calculate the gravitational potential energy of the child
relative to the ground.

Answer 1

980J

Step-by-step explanation:

Given parameters:

Mass of the child = 25kg

Height of the slide = 4m

Unknown:

Gravitational potential energy = ?

Solution:

To solve this problem, we have to use the expression below:

Gravitational potential energy is the energy due to the position of a body.

It is mathematically expressed as;

G.PE = mgh

m is the mass

g is the acceleration due to gravity

h is the height

G.PE = 25 x 9.8 x 4= 980J
