    View the file below. Disregarding friction, how much force does each board of wood put on the 100 N ball?

    I got 70.71 N by doing 100cos(45). I have no idea whether or not this is correct.

    There are two boards exerting contact forces on the ball. Call these each F. Draw a free body diagram, and write down the equations in order for the ball to be in equilibrium.
