Haha i did it.. thanks.(adsbygoogle = window.adsbygoogle || []).push({});

Another:

A force of 600 N stretches a certain spring a distance of 0.3m .

What is the potential energy of the spring when it is stretched a distance of 0.3m ?

What is its potential energy when it is compressed a distance of 4.0 m ?

I know I am supposed to use the Spring Potential Energy equation (1/2)*k*x^2 but how do I find k? Is it 600N?? I've tried 27 and 600 and those are incrorect.
