1. The problem statement, all variables and given/known data A constant force of 1i - 5j -8k moves (1,-4,2) (-3,2,-1), what is the work done on the particle? 2. Relevant equations Avector*Bvector=ABsinθ ?? I think? 3. The attempt at a solution I really am quite lost... but I found the coordinates for the position vector... (-3-1)i + (2--4j) + (-1-2)k and the magnitude of the position vector is 7.81 so the unit vector is -.512i + .768j -.384k... am I on the right track here?
