| Ks| / \

a) |xxxx[] b) |/ \x=2.8m

<----x=0---->

figure a) a box connected to the wall by a spring.

figure b) a graph of K over x where K is 0 at x=0 and at x = 2.8. Ks = 2.4 J

1) What is the magnitude of F?

2) What is k(spring coefficient)?

**Jin**, Saturday, October 24, 2009 at 9:00pmI figured it out. All you need to do is use Wnet = Wforce + Wspring = Kf - Ki twice. Once for the entire displacement Kf - Ki = 0 and once for half way where Kf - Ki = 2.4. Both times you will have a k(spring constant term) in the equation and if you solve for them and set equal you can solve for Force. Thanks anyway bobpursley.
