Question

If a spring constant of 128N/m is compressed by 0.18 m , how much potential energy is the spring?

Answer 1

2.1J

Step-by-step explanation:

Given parameters:

Spring constant = 128N/m

Compression = 0.18m

Unknown:

Potential energy of the spring = ?

Solution

The potential energy of the spring is the elastic potential energy within the spring.

To solve this;

Elastic potential energy =
`(1)/(2)` k e²

k is the spring constant

e is the compression

Now;

Elastic potential energy =
`(1)/(2)` x 128 x 0.18² = 2.1J
