Question

A man is dragging a trunk up the loading ramp of a mover's truck. The ramp has a slope angle of 20.0 How large will the component Fy perpendicular to the ramp then be? large a force F is necessary for the component Fx parallel to the ramp to be 60.0 N?, and the man pulls upward with a force F whose direction makes an angle of 30.0 with the rampHow large a force F?  is necessary for the component Fx parallel to the ramp to be 60.0 N?How large will the component Fy perpendicular to the ramp then be?

Explanation / Answer

1) a.
Fx = Fcos30.0deg
60.0N = Fcos30.0deg
F = 60.0N/cos30.0deg
F = 69.3 N ANSWER

b. Fy = Fsin30.0deg
Fy = 69.3 N sin 30.0 deg
Fy = 34.6 N ANSWER
