Answer:
The bell has a potential energy of 8550 [J]
Explanation:
Since the belt is 45 [m] above ground level, only potential energy is available. And this energy can be calculated by means of the following equation.
![E_{p}= W*h\\E_{p} = 190*45\\E_{p}=8550[J]](https://tex.z-dn.net/?f=E_%7Bp%7D%3D%20W%2Ah%5C%5CE_%7Bp%7D%20%3D%20190%2A45%5C%5CE_%7Bp%7D%3D8550%5BJ%5D)
