The work required to strecth the spring is about 2.0 Joules

<h3>Further explanation</h3>
Let's recall Elastic Potential Energy formula as follows:

<em>where:</em>
<em>Ep = elastic potential energy ( J )</em>
<em>k = spring constant ( N/m )</em>
<em>x = spring extension ( compression ) ( m )</em>
Let us now tackle the problem!

<u>Given:</u>
spring constant = k = 2500 N/m
extension = x = 4.00 cm = 4.00 × 10⁻² m
<u>Asked:</u>
work required = W = ?
<u>Solution:</u>
<em>We will calculate the </em><em>work</em><em> required to stretch the spring as follows:</em>
