A man is dragging a trunk up the loading ramp of a mover's truck. The ramp has a slope angle of 20.0 degrees and the man pulls upward with a force of magnitude 381N whose direction makes an angle of 30.0 degrees with the ramp.
a) Find the horizontal component of the force?
b) Find the vertical component of the force?
