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.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

answer: d. $20
