Answer:
<h2>117.45 J</h2>
Explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
GPE = 2.25 × 10 × 5.22
We have the final answer as
<h3>117.45 J</h3>
Hope this helps you
