This is the problem:
A woman exerts a horizontal force of 9 pounds on a box as she pushes it up a ramp that is 6 feet long and inclined at an angle of 35 degrees above the horizontal.
First state the displacement vector and the force vector, considering the ramp going up from left to right and the level ground under the ramp to be the positive x-axis.
This is how I've solved it. Since the problem says "horizontal" force, I've assumed her force vector over the displacement to look like this:
\begin{align} \langle 9,0\rangle,\tag{1} \end{align} which makes sense. No problems there.
Now when it comes to the displacement vector, why is it that in this case, the following is wrong?
\begin{align} \bigg\langle 6\cos\left(\frac{35\pi}{180}\right),6\sin\left(\frac{35\pi}{180}\right)\bigg\rangle\tag{2} \end{align}
Thanks,
