Spring energy problem at an incline with friction

  1. Nov 12, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    Et = Ek + Eg + Ee

    3. The attempt at a solution

    Et=mgh+1/2k1 Δx12 +1/2k2Δx22

    196h+400+600 = ET



    ...and that's when I realized I must have done something wrong. Sorry, i'm kind of bad at this stuff. Please help

    Why do you think you have done something wrong?
    h, I assume, is the distance the mass falls. What is the relationship between h and x2?
