Answer:
<h3>The answer is 900 J</h3>
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 = 45 × 10 × 2
We have the final answer as
<h3>900 J</h3>
