A force is applied to a 3.61kg- radio-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 figure (Figure 1) .Suppose the model car is initially at rest at x=0 and F> is the net force acting on it.

    What is the work done by the force when the car moves from x=0 to x=3? I have tried to find the area of the graph using the area of trapezoid .5(b1+b2)*2 and got F=4 and distance is 3 = W=12 J but I keep getting the wrong answer

    Use the work-energy theorem to find the speed of the car at x=3.0m How do we go about this?
