The free-body diagram for the stone is shown on the right, withFGbeing the force applied to the stone, NFGthe downwardnormal force of the ceiling on the stone, mgGthe force of gravity, andGfthe force of friction. We take the +xdirection to be horizontal to the right and the +ydirection to be up. The equations for the xand the ycomponents of the force according to Newton’s second law are: cossin0xyNFFfmaFmgθ
