A child applies a force F⃗ parallel to the x-axis to a 10.0-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.http://tinypic.com/view.php?pic=xauk94&s=7Use the work-energy theorem to find the speed of the sled at 1.0m?????
