## Homework Statement

force vector F = 700[-0.25, 0.433, 0.866].

vector A = [-4, 4, 2]

a)What is the component of F that is parallel to A?

b}And what is component of F that is perpendicular to A?

## Homework Equations

[tex]A\bullet F = |A||F|\cos{\theta}[/tex]

When two vectors are parallel:

[tex]A\bullet B = |A||B|| [/tex]

When two vectors are perpendicular

[tex]A\bullet B = 0 [/tex]

## The Attempt at a Solution

I'm not sure if I should use the dot product to find the component but I figure that would be the simplest way to do so.

A = [-4, 4 ,2] = 6[-2/3, 2/3, 1/3]

The parallel force vector = s[-2/3, 2/3, 1/3]

That's all I have right now. If I use the dot product equation, both sides of the equation will come to the same term and cancel each other out. I think my definition for the parallel force vector is too general as s could be any scalar.
