Homework Help: Spring constant.

  1. Apr 8, 2008 #1
    This is a question on my physics homework.

    If a trampoline has a spring constant of 52000 N/m, how far does it stretch?

    What equation do I use?

    The spring constant tells you how force (N) is required to stretch a spring 1 unit of length (m).

    What do you mean how far does it stretch? What's on it? If nothing is on it, then it won't stretch at all.

    i think you need to at least give us more info.....you're missing force for this problem.
    F = -kx
    you're looking for x, but to find it, we need F.

    Since no specific force is given, the answer is it will stretch 1 m for every 52000 N applied to the trampoline.

    oooh, that's it!!!! :)
    cool, you taught me something too.
