First we need to convert everything into SI units.
The initial volume of the gas is (keeping in mind that
:
The initial pressure of the gas is (keeping in mind that
:
The final pressure of the gas is (keeping in mind that
)
At constant temperature, the product between pressure and volume of the gas is constant, so we can write
from which we find the final volume of the gas:
From the calculations, the mass of the pole is 82 Kg.
<h3>What is potential energy?</h3>
The term potential energy has to do with the energy that is possessed by a body by virtue of its position.
Given that;
height = 6.15 m
PE = 4942 J
mass = ??
g = 9.8 m/s^2
Now
PE = mgh
m = PE/gh
m = 4942 J/9.8 m/s^2 * 6.15 m
m = 82 Kg
