Unformatted text preview: initial kinetic plus the work done: K = K + W . Speed of a car Now try to use these ideas to answer the following questions. A car moves along a straight line in the positive x direction. The net force on the car varies as the car moves, and is plotted as a function of position for two different situations in the graphs. 1. On each graph, shade in the area that represents the work between positions A and B. 2. Is the work positive or negative? 3. At which point is the car moving faster (circle one)? Top graph: A B Bottom graph: A B Explain your reasoning: Force position x x W F net...
