A man is dragging a trunk up the loading ramp of a mover's truck. The ramp has a slope angle of , and the man pulls upward with a force whose direction makes an angle of with the ramp.
1. How large a force is necessary for the component parallel to the ramp to be 6 ?
2. How large will the component perpendicular to the ramp then be?
I've got the answers: 69.3 N and 34.6 N respectively, but I don't know how to actually work the problem and get those answers.
I think that is the same as and , but I don't know if that helps me or not.
