A child applies a force parallel to the x-axis to a 9.00- 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.
