The gravitational potential energy is 25.6 J

Explanation:

The gravitational potential energy (GPE) of an object is given by:

$GPE = mgh$

where

m is the mass of the object

g is the gravitational field strength

h is the height of the object above the ground

In this problem, we have

m = 8 kg is the mass of the brick

g = 1.6 N/kg is the gravitational field strength on the moon

h = 2 m is the height of the brick above the ground

Substituting,

$GPE=(8)(1.6)(2)=25.6 J$
