## Homework Statement

Find the work done by a force of 3 newtons acting in the direction 2i + j + 2k in moving an object 2 meters from (0, 0, 0) to (0, 2, 0).

## Homework Equations

Commonly known vector operations.

## The Attempt at a Solution

I found the displacement vector to be 2j.

My problem is figuring out how to represent the direction and magnitude of force as an actual vector.

The answer is (6*SQRT 5)/5 Joules. I don't understand how.
