Homework Statement


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


Homework Equations





The Attempt at a Solution

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
