Answer:
Step-by-step explanation:
Given that :
There is a bell at the top of a tower that is 45m in height. The mass of the bell is 190N.
To calculate :
Gravitational potential energy of the bell.
Solution :
For calculating gravitational potential energy the required formula is,
Where,
- m is mass
- g is Acceleration due to gravity = 9.8 m/s²
- h is height in metres.
Plugging the required data,



Henceforth, the gravitational potential energy of the bell is 83,790 joules
