Spring Constant

  1. Jul 26, 2008 #1
    1. The problem statement, all variables and given/known data

    A person who weighs 760 N steps onto a spring scale in the bathroom, and the spring compresses by 0.82 cm.

    a. What is the spring constant?

    B. What is the weight of another person who compresses the spring by 0.34 cm?


    2. Relevant equations

    FApplied = kx

    3. The attempt at a solution

    I'm having trouble with part A. I got the correct answer of 315.12195N for part B.

    For part a i set it up as 760 = .82k and got 926.829 N/m but webassign will not accept it as correct. It has to be right because I got part B of the question correct with it.

    I tried 927, 926.8 and 926.82926 N/m. Am I doing something wrong?

    Be careful with units.
