Should be simple problems

  1. Oct 21, 2007 #1
    1. The problem statement, all variables and given/known data

    A 22.0 kg child slides down a slide that makes a 37.0° angle with the horizontal. What is the magnitude of the normal force that the slide exerts on the child?

    2. Relevant equations

    Fnormal= mg cos (x)

    3. The attempt at a solution

    Fnormal= 22.0kg(-9.80m/s^2) (cos 37)= 172N...but that's not right

    I'm so confused..thanks for helping

    ah, I see I didn't read the question carefully enough @_@ I put -172N for the answer instead of 172. Thanks!
