Question

A man is dragging a trunk up the loading ramp of a movers truck. The ramp has a slope angle of 20.0°, and the man pulls upward with a force → F F→ whose direction makes an angle of 30.0° with the ramp. How large a force → F F→ is necessary for the component Fx parallel to the ramp to be 90.0 N

Answer 1

Answer:103.92 N

Step-by-step explanation:

Given

Ramp angle
`=20^(\circ)`

Force required to create
`F_x=90 N`

Let the Force be F

`F\cos 30=90`

`F=(90)/(\cos 30)=103.92 N`
