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

  1. Apr 4, 2009 #1
    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.

    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
