Question
Please answer the following 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 degree, and the man pulls upward with a force R rightarrow whose direction makes an angle of 30.0 degree with the ramp in (Figure 1) How large a force F rightarrow is necessary for the component F_z parallel to the ramp to be 90.0 N? Express your answer with the appropriate units. How large will the component F_y perpendicular to the ramp then be? Express your answer with the appropriate units.Explanation / Answer
a) Fx = F cos 30
as per the question Fx = 90
F cos 30 = 90
F = 103.92 N
b) Fy = F sin 30
= 103.92 sin 30 = 51.96 N
