Question

There is a bell at the top of a tower that is 45m in height. The mass of the bell is 190N. Calculate the gravitational potential energy of the bell.​

Answer 1

The gravitational potential energy of the bell can be calculated using the formula GPE = mgh, where m is the mass of the bell, g is the acceleration due to gravity, and h is the height of the tower. Plugging in the given values, we get:

GPE = 190 N x 9.8 m/s^2 x 45 m

GPE = 83,220 J

Therefore, the gravitational potential energy of the bell is 83,220 J.

Answer 2

• 83,790 joules

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,

• G.P.E = mgh

Where,

• m is mass
• g is Acceleration due to gravity = 9.8 m/s²
• h is height in metres.

Plugging the required data,

`{ \sf{GPE }} = 190 * 9.8 * 45`

`{\sf{GPE }}= 1862 * 45`

`{\sf{GPE = \: } }83,790 { \sf{Joules}}`

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