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 .

Calculate the work done by the force F when the sled moves from x=0 to x=8.0 m.

Calculate the work done by the force F when the sled moves from x=8.0 m to x =12.0 m.

Calculate the work done by the force F when the sled moves from x=0 to x =12.0 m.
