A child applies a force F parallel to the x-axis to a 5.00-kg sled moving on the frozen surface of a small pond. As the child controls the speed of the sled, the x- component of the force she applies varies with the x- coordinate of the sled as shown in figure (Figure 1). Suppose the sled is initially at rest at x=0. You can ignore friction between the sled and the surface of the pond.
