A force is applied to a 2.5 kg radio-controled model car parallel to the axis as it moves along a straight track. The component of the force varies with the coordinate of the car as shown in figure (Eigure 1). Suppose the model car is initially at rest at 20 and i in the not force acting on it Part A Figure 1 of 1 Use the work energy theorem to find the speed of the car at 2-3.0 m.
