Hi all,
I've been trying (unsuccessfully!) to rearrange the following equation so that H is the subject:
mgH = [k(H - L)^2] / 2
(Where ^2 means squared.) I also have some test data which shows that if m = 50, g = 9.8, k = 40 and L = 20, H should equal 57.5, or thereabouts.
I'm going to need the equation in a couple of hours and am stressing out, so any help you can offer would be greatly appreciated.
