Easy Spring Constant Question

  1. Feb 11, 2008 #1
    [SOLVED] Easy Spring Constant Question

    A particular spring has a force constant of 2.5 x 10^3 N/m. (a) How much work is done in stretching the relaxed spring by 6.0 cm? (b) How much more work is done in stretching the spring an additional 2.0 cm?

    I am using W=1/2kx^2 but I am not completely sure.

    Well the answer are a. 4.5 J and b. 3.5 J. When I plug in I get W=1/2(2500)(8)^2. I am getting the answers 45000 and 35000. I think I am using the right equation I am just multiplying wrong or something..
