Homework Statement
A boulder of weight w rests on a hillside that rises at a constant angle (alpha) above the horizontal, as shown in the figure. The boulder's weight is a force on the boulder that has a direction vertically downward.
In terms of alpha and w, what is the component of the weight of the boulder in the direction parallel to the surface of the hill?
Homework Equations
The Attempt at a Solution
I put w/sin(alpha) but this is wrong. As you can see I made the component parallel to the slope of the hill x so that means that sin(alpha)=w/x...solve for x and I get x=w/sin(alpha).
Apparently this is totally wrong.
I attached the diagram to the problem. Thanks for the help
