## Homework Statement

Calculate the work done if a 25N force acting in a direction of vector (2,3,-1) moves an object from P(2,-3,1) to Q(5,0,2).

## Homework Equations

Work = Force (dot) Displacement

## The Attempt at a Solution

Well force is 25N. But as for displacement, do I just find the displacement of the points P and Q, but then what's the direction vector (2,3,-1) for? I'm just a bit confused on this.
