<u>P.E (Potential Energy) = 33868.8 J</u>
<u>Explanation:</u>
The formula to calculate Potential energy is:
PE = mgh
where PE = potential energy
m = mass of an object
g = acceleration due to gravity
h = height of the object
Here, m = 64 kg
g = 9.8
h = 54 m
So, substituting the values in the formula:
PE = mgh
= 64 × 9.8 × 54
= <u> 33868.8 J</u>
