Homework Help: Board wedged with a spring

  1. Dec 4, 2006 #1
    1. The problem statement, all variables and given/known data
    A 11.5 kg board is wedged into a corner and held by a spring at a 50.0° angle, as the drawing shows. The spring has a spring constant of 206 N/m and is parallel to the floor. Find the amount by which the spring is stretched from its unstrained length.

    2. Relevant equations


    3. The attempt at a solution

    I tried doing sin50(11.5kg)/-206 but that didn't work
