Answer:
<h2>57,500 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = 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
PE = 25 × 10 × 230 = 57,500
We have the final answer as
<h3>57,500 J</h3>
