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 ? of magnitude 375N whose direction makes an angle of 30.0 ? with the ramp.
A) Find the horizontal component of the force F?
B) Find the vertical component of the force?
