5. ESSM Suppose in Figure 6.2 that +1.10 x 10³ J of work is done by the force F (magnitude = 30.0 N) in moving the suitcase a distance of 50.0 m. At what angle is the force oriented with respect to the ground? Theore F cos 0 (b) F cos 0 961 FIGURE 6.2 (a) Work can be done by a force F that points at an angle 0 relative to the displacement 3. (b) The force component that points along the displacement is F cos 0.
