A7.9 kg object is moving in the positivex direction. When it passes through x- 0, a constant force directed along the axis begins to act on it. The figure here gives its kinetic energy K versus position x as it moves from x-O to x-5.0 m; Ko - 24 . The force continues to act. What is speed v when the object moves back through x-3,0 m?
