1. A man is dragging a trunk up the loading ramp of a mover's truck. The ramp has a slope of 200, and the man pulls upward with a force 1:4 whose direction makes an angle 30.0 with the ramp (Figure 1). (a) How large a force f is necessary for the component Fm parallel to the ramp to be 60.0N? (b) How large will the component Fy perpendicular to the ramp then be? 20.0c Figure 1: Man Pulling Trunk Up the Loading Ramp 2' Explain (in your own words) what a free body diagram is used for
