(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Seven and one half foot pounds of work is required to compress a spring 2 inches from its natural length. Find the work required to compress the spring an additional one-half inch

2. Relevant equations

W=kd

W=∫f(x)dx

3. The attempt at a solution

7.5=W

∫kxdx from (0,1/6)

=(kx^(2))/2 from (0,1/6)

=k/72=7.5

K=540

∫(540x)dx from (4/24, 5/24)

The rest is just algebra that's irrelevant; did i set up the problem right?
