Answer:

0.55m

Explanation:

Given parameters:

Spring constant  = 1800N/m

Elastic potential energy  = 270J

Unknown:

extension = ?

Solution:

To solve this problem, we use the formula of the elastic potential energy;

     E. P  = [tex]\frac{1}{2}[/tex] k e²  

E.P is the elastic potential energy

k is the spring constant

e is the extension

            270  =  [tex]\frac{1}{2}[/tex] x 1800 x e²  

                e  = 0.55m
