Aman 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?

a.69.3 N

b.34.7 N

Step-by-step explanation:

We are given that

Angle of inclination of the ramp=

Force F makes an angle with ramp=

The component  of F parallel to the ramp =

a.We have to find the value of when its horizontal component is 60 N.

We know that

b.We have to find perpendicular to the ramp.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
