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

Respuesta :

Answer:103.92 N

Explanation:

Given

Ramp angle[tex]=20^{\circ}[/tex]

Force required to create [tex]F_x=90 N[/tex]

Let the Force be F

[tex]F\cos 30=90[/tex]

[tex]F=\frac{90}{\cos 30}=103.92 N[/tex]
