A force F is applied to a 2.O-kg m dio-controlled model car parallel to the x-axis as it moves along a straight track. The x-component of the force varies with the x-coordinate of the car as shown in Fig. 6.32. Calculate the work done by the force 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 = 4.0 m to x = 7.0 m;
(d) x = 0 to x = 7.0 m;
(e) x = 7.0mtox = 2.0m
