A child applies a force F? 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 the figure (Figure 1) Part A Calculate the work done by the force F? when the sled moves from x=0 to x=8.0m. Express your answer using two significant figures. Part B Calculate the work done by the force F? when the sled moves from x=8.0m to x =12.0m. Express your answer using two significant figures. Part C Calculate the work done by the force F? when the sled moves from x=0 to x =12.0m. . Express your answer using two significant figures.
