Homework Help: Kinetic Energy Problem

  1. Dec 3, 2008 #1
    An 9.1 kg object is moving in the positive direction of an x axis. When it passes through x = 0, a constant force directed along the axis begins to act on it. The figure below gives its kinetic energy K versus position x as it moves from x = 0 to x= 5.0 m; K0 = 26.5 J. The force continues to act. What is v when the object moves back through x = -3.0 m?
