1. The problem statement, all variables and given/known data Figure 8-17 shows one direct path and four indirect paths from point i to point f. Along the direct path and three of the indirect paths, only a conservative force Fc acts on a certain object. Along the fourth indirect path, both Fc and a conservative force Fnc act on the object. The change in ME (in Joules) in going from i to f is indicated along each straight line segment of the indirect paths. (a) what is change in ME in moving from i to f along the direct path (b) what is change in ME due to Fnc along the one path where it acts. This is a conceptual question but I don't get it. 2. Relevant equations change in ME=change in K + change in U=0 3. The attempt at a solution Change in ME should equal zero for conservative forces. But the diagram has a bunch of numbers that neither add up to zero or are 0. http://i2.photobucket.com/albums/y25/keltix/fig8-17question1.jpg"
