4.4 • 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 É whose direction makes an angle of 30.0° with the ramp|(Fig. E4.4). (a) How large a force F is necessary for the component Fx parallel to the ramp to be 60.0 N? (b) How large will the component Fy perpendicular to the ramp then be?
