If you are referring to the potential energy of the bell then the answer would be:
8,379 kg.m²/s² or 8,379 Joules
This is how it was solved:
Potential energy is stored energy in an object in relation to its position. In this case, we are talking about gravitational potential energy.
This can be solved with the equation:
[tex]PE_{grav}= mgh[/tex]
Where:
PEgrav potential energy
m = mass
g = 9.8 m/s²
h = height
Now all you do is plug in what you know into the equation:
Given:
m = 19 Kg
g = 9.8 m/s² (This is the constant acceleration due to gravity on Earth)
h = 45 m
Solution:
[tex]PE_{grav}= mgh[/tex]
[tex]PE_{grav}= (19kg)(9.8m/s^{2})(45m)[/tex]
[tex]PE_{grav}= 8,379kg.m^{2}/s^{2}[/tex] or [tex]8,379 Joules[/tex]
The energy of the bell weighs 19kg at the top of a tower that is 45m high is [tex]\rm \bold { 8379 kgm^2/s^2}[/tex].
Potential Energy:
The energy that depends on the relative position of different part of system. Here the energy is stored in the bell due to it's gravitational force that is applying on it due to its relative height.
The formula of gravitational energy is,
[tex]\rm \bold {U = mgh}\\\\[/tex]
Here,
U = Gravitation Energy
m = mass of object = 19 kg
g = gravitational force of the Earth = 9.8 m/[tex]\rm \bold s^2[/tex]
h = Height of object = 45 m
Put the value to the formula
[tex]\rm \bold {U = 19 kg\times9.8m/s^2\times 45m }\\\\\\\rm \bold {U = 8379 kgm^2/s^2}[/tex]
Hence, we can say that the energy of the bell weighs 19kg at the top of a tower that is 45m high is [tex]\rm \bold { 8379 kgm^2/s^2}[/tex].
