Chapter 6, Problem 6.43E

A force $\stackrel{\to }{F}$ is applied to a 2.0-kg, radio-controlled model car parallel to the x-ax is as it moves along a straight track. The x-component of the force varies with the x-coordinate of the car (Fig. E6.43). Calculate the work done by the force $\stackrel{\to }{F}$ when the car moves from (a) x = 0 to x = 3.0 m; (b) x = 3.0 m to x = 4.0 m; (c) x = x = 4.0 m to x = 7.0 m; (d) x = 0 to x = 7.0 m; (e) x = 7.0 m to x = 2.0 m.
