1. The problem statement, all variables and given/known data The graphs show the force Fi (in pounds) required to move an object 9 feet along the x-axis. Order the force functions from the one that yields the least work to the one that yields the most work without doing any calculations. Explain your reasoning. 2. Relevant equations http://img227.imageshack.us/img227/9098/picrn.png [Broken] 3. The attempt at a solution This is in my Calc 2 book and I don't know much or anything about physics, but I'm assuming you can use something similar to the concept of vectors to find this out? I hav no real idea how to come to a solution to this problem.
