Problem Details

The figure is the force-versus-position graph for a particle moving along the x-axis. Determine the work done on the particle during each of the three intervals 0-1 m, 1-2 m, and 2-3 m. A graph shows the x-component of force as a function of position. Position is measured from 0 to 3 meters on the x-axis. The force is measured from -4 to 4 newtons on the y-axis. In the distance interval from 0 to 1.5 meters, the x-component of the force equals 4 newtons. In the distance interval from 1.5 to 2 meters, the x-component of the force equals -4 newtons. In the distance interval from 2 to 3 meters, the x-component of the force linearly rises from -4 to 0 newtons. At the distances beyond 3 meters, the force is 0 newtons.
