Question

A7.9 kg object is moving in the positive x 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 fromx-O to x= 5,0m: Ko - 24 1. The force continues to act.
What is speed v when the object moves back through x-3.0 m?
