== 2. An object needs to be moved from point A = (10,-2,-4) to point B = (5, 5, 6) in R. You have the choice of doing so by applying 100 N of force in one of three directions, namely the directions of the vectors = (-1, 1, 1). = (-1, 1, 2), or us = (-1, 1, 3). A. Calculate the projections of the vectors U1, U2, and 3 onto the displacement vector pointing from A to B. B. Which of the three choices of moving the object accomplishes the most work? Explain. C. Bonus: Of all the vectors x = (-1, 1, A), where A can be any real number, which one accomplishes the most work when you apply 100 N of force in the direction of x to move the object from A to B?
