Spring force (F) is related to "stretch" (x) by use of a "stiffness constant" (k):

F = kx

60 = k(0.8)    ->      k = 60 / 0.8     ->     k = 75

that's all?

anonymous · Answer

This makes sense because more force is needed to stretch or compress a spring a greater distance.

I thought there would be more though

Yes,  This looks harder than it actually is!    Funny that way!

heh alright next one coming up :D
