Hi Sierra;

Force=45N, 35-degrees above horizontal

Distance=9m

Work=(force)(distance)

The issue created by the degrees above horizontal is that a triangle is created. We need to understand the horizontal force of this triangle.

The hypotenuse is = 250N

We need the value of the adjacent...

adjacent/hypotenuse

Therefore, we need the value of the cos of 35-degrees.

45N (cos 35-degrees)=45N(0.82)=36.9N

Work=(36.9N)(9m)=332 joules
