Inclined plane

  1. Oct 8, 2009 #1
    1. The problem statement, all variables and given/known data
    the weight of a box on a plane inclined at 30 def is represented by the vector W. What is the magnitude of the component of the weight that acts parallel to the incline.
    Answer is given in terms of W
    possible anwsers .5W 1.5W .87W and W

    2. Relevant equations

    3. The attempt at a solution
    M x g x sin(30)= 4.9
    not sure what formula is needed to be used here

    W = mg. So
    W*sinθ = ?

    You don't know M, but you do know that W = M*g
    so you have W*sin(30) = 0.5*W
