To stretch a spring a distance 3.09cm from its unstretched length, an amount of work of11.1j must be done. How much work must be done to compress this spring a distance 4.08 from its unstretched length?
I have been using the equation
k=Fx/x
W=(1/2)kx2^2-(1/2)kx1^2
11.1=(1/2)(Fx/.0309)*(.0309^2)-(0)
Fx=718N
So I plug 718N into
W=(1/2)(718/.0408)*(.0408^2)
I get 14.6 but it is still not the right answer someone please help
