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 377N whose direction makes an angle of 30.0 degrees with the ramp.Find the horizontal component of the force. Find the vertical component of the force.
The pulling force makes an angle of 20 + 30 = 50 degrees with the horizontal.
The vertical component is 377 sin 50 and the horizontal component is 377 cos 50.
You don't need to concern yourself with free body diagrams or friction to get those numbers. All you are doing is resolving one force along two different axes.
