Consider Theorem 7.3, given below. If a constant force F is applied to an object, and the resulting movement of the object is represented by the displacement vector d, then the work performed by the force is Work - F. d. The problem that follows is a problem you may have worked previously in Section 2.5. Solve the problem by first expressing the force and the displacement of the object as vectors in terms of the unit vectors i and j. Then use Theorem 7.3 to find the work done. A package is pushed across a floor a distance of 70 feet by exerting a force of 35 pounds downward at an angle of 25° with the horizontal. How much work is done? (Round your answer to the nearest hundred foot-pounds.) ft-lb
