Question

Calculate the potential energy of a 300 gram volleyball that is 15 meters in the air. (g = 9.8 m/s2)

explain why if you can, thank you :)

Answer 1

The book gravitational potential energy is 44.1 Joules fear

Step-by-step explanation:

Given:

Mass of volleyball, m = 300g = 300 ÷ 1000 = 0.3 kg

height, h = 15 m

To Find:

Potential Energy = ?

Solution:

Gravitational Potential Energy :

Gravitational potential energy is energy an object possesses because of its position in a gravitational field.

Formula is given by

`\textrm{Gravitational Potential Energy}= m* g* h`

Where,

m = mass

g = acceleration due to gravity = 9.8 m/s²

h = height

Substituting the values we get

`\textrm{Gravitational Potential Energy}= 0.3* 9.8* 15\\\\\textrm{Gravitational Potential Energy}=44.1 Joules`

The book gravitational potential energy is 44.1 Joules.
