A man is dragging a trunk up the loading ramp of a mover’s truck. The ramp has a slope angle of 20.0 , and the man pulls upward with a force F S whose direction makes an angle of 30.0 with the ramp . (a) How large a force F S is necessary for the component Fx parallel to the ramp to be 90.0 N? (b) How large will the component Fy perpendicular to the ramp be then?
