Answer:

2.1J

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  = [tex]\frac{1}{2}[/tex]  k e²  

k is the spring constant

e is the compression

 Now;

     Elastic potential energy  =  [tex]\frac{1}{2}[/tex] x 128 x 0.18²  = 2.1J
