Did not realize I had to multiply my F vector by 800. And based on your solution, the angle is found to be 34.4. Thanks much!

I think I got it! Except that the question states that the vector V is in the xy plane: cos^-1((<3 , 5> x <0.00375 , 0.00625>)/(sqrt34 x sqrt 50))=89.94

I can find the angle between the vectors. Yes? But what I am confused about is what vectors to use.
