2. Relevant equations

I know that

W = Fd where here it is

W = F * [tex]{\rightarrow}{\}[/tex]AB

Also, that

(im sorry, this looks really ugly)

[tex]\stackrel{v\rightarrow}{}[/tex] = ||v||(cos[tex]\alpha[/tex][tex]\stackrel{i\rightarrow}{}[/tex]+sin[tex]\alpha[/tex][tex]\stackrel{j\rightarrow}{}[/tex])

||v|| = sqrt(a^{2}+b^{2})

3. The attempt at a solution

I get stuck fairly quickly on this problem, my professor never went on it in class.

using the second equation, I get to the point of

v = (sqrt13)(cos+sin)

I am not sure what goes into the cos and sin portion of the problem, I am assuming it has something to do with the coordinates it gives, but other than that, I have no idea.
