Problem
A 1.6 kg particle moving along the x-axis experiences the force shown in the figureThe graph shows a force F subscript x baseline as a function of the x coordinate. The force is measured from minus 10 to 10 newtons on the y axis. The coordinate is measured from 0 to 4 meters on the x axis. The force linearly decreases from 10 newtons at 0 to minus 10 newtons at 4 meters. At the x coordinate greater than 4 meters the force is 0.. The particles velocity is 4.6 m/s at x = 0 m.
