1. The problem statement, all variables and given/known data A force of f= i + 2j- 3k is applied to a particle that moves 10 feet in the direction of i + j. How much work is done? 2. Relevant equations W= ||F|| dot product d 3. The attempt at a solution D= 10 cos 45 i + 10 sin 45 j D= 5sqrt(2) i + 5 sqrt(2) j F= i + 2j - 3k W= ||F|| dot product d W= sqrt(14) dot product (5sqrt(2)i + 5sqrt(2)j) W= 5sqrt(28) + 5 sqrt(28) W= 10sqrt(28) W= 20sqrt(7) Is this even right? Thanks!
