Question

A man is dragging a trunk up the loading ramp of mover's truck. The ramp has a slope angle of 20 degree, and the man pulls upward with a force F whose direction makes an angle of 30 degree with ramp. a) How large a force F is a necessary or the component F, parallel to the ramp to be 60N? b) How large will the component F, then be?

Answer 1

I added the two angles to make 50 degrees and did 60cos(50) and 60sin(50) and got about 39 and 46. Is this correct?

Answer 2

using 50 degrees finds the component of force that is parallel to the ground, we need to find the component parallel to the ramp
