I'm not understanding the following formula. I'm a computer programmer and was given a set of formulas to have an application to solve; however I'm not completely understanding how this works. I'm just looking for a step by step way to solve this and an explanation on why there are 3 assignment operators within the formula. This is the first I've seen of this kind. I plan to further my education in Physics, but this is above my head right now and I'm looking for some assistance. F = ma = m(d^2x)/(dt^2) = -kx Thanks in advance, Jamie PS - I don't know how to work the super script or the fraction bar available. Sorry.
