1. The problem statement, all variables and given/known data

I have this vector field equation, the first part of the question is to find the potential equation for it, I found it.
The second part of the question is to find the work of the field through this path.
My idea is to plug t in the r equation, because I'm not sure but I think (x,y,z)=(component of r), is that right? and that way I find the start point of the path and the end point, plug it into the potential equation and that's it, is that right?

2. Relevant equations

3. The attempt at a solution

10x, it seemed so easy, and they gave 10 points for it (it's a question from a test), so I got confuse...
