Spring Constant (this is really easy, I'm just dumb haha)

[pippintook]

A spring 150-cm long extends to a length of 155 cm when it supports a load of 55 N. Determine the spring constant.

F = kx

x₁= 1.5 m
x₂= 1.55 m
F = 55 N
k = ?

Now, "x" in F = kx is x₂-x₁, right? So the formula would be 55 = .05k?

Sorry, I know this is simple, I just am having a momentary lapse.

Perfectly correct.

Awesome. That's what I thought, but when I was experimenting with springs the constant was always a lot smaller so I got confused :P
