Question

Use the data provided to calculate the gravitational potential energy of each cylinder mass. Round your answers to the nearest tenth.

3 kg: ____kJ

6 kg: ____kJ

9 kg: ____kJ

Answer 1

Answer: 14.7kJ, 29.4kJ, 44.1kJ

Step-by-step explanation:

The gravitational potential energy is the energy that a body or object possesses, due to its position in a gravitational field.

In the case of the Earth, in which the gravitational field is considered constant, the value of the gravitational potential energy
`U_(p)` will be:

`U_(p)=mgh`

Where
`m` is the mass of the object,
`g=9.8m/s^(2)` the acceleration due gravity and
`h=500m` the height of the object.

Knowing this, let's begin with the calculaations:

For m=3kg

`U_(p)=(3kg)(9.8m/s^(2))(500m)`

`U_(p)=14700J=14.7kJ`

For m=6kg

`U_(p)=(6kg)(9.8m/s^(2))(500m)`

`U_(p)=29400J=29.4kJ`

For m=9kg

`U_(p)=(9kg)(9.8m/s^(2))(500m)`

`U_(p)=44100J=44.1kJ`
