3. (20 pts) An object of mass m = 3.00 kg initially at rest (Vo = 0.00 m/s) and located at X, = 0.00 m is acted on by a variable one-dimensional force F in the x direction. The force F as a function of position x is given by the graph shown in Figure 3. If this is the only force that acts on the object, use the graph to estimate the velocity v of the object in the x direction when the object reaches the position x = 8.00 m. Make use of the Work-Kinetic Energy Theorem and your knowledge of work for a variable force. Report your answer to three significant figures.
