Ok, so I really need some help with this one. Find the work done by a 30N force acting in the direction of the vector (-2,1,5), which moves an object from A(2,1,5) to B(3,-1,2). The distance in meters. I get pretty close, but can never quite get the right answer. Any help is appreciated, (+ rep) for correct complete solution. If there is no reply after today (May 28 Neofriends time) then, don't worry about it, it's gonna be too late so don't reply.
