Given the graph below with the initial velocity, vi = -8 m/s, the object starts with one value of constant acceleration and stops at 2.3 seconds. Then, the value of its acceleration changes to a different acceleration. Finally, at t1 = 6.8 seconds, it travels at a constant (final) velocity. After t2 = 10.3 seconds, the average velocity of the entire trip is 3.8 m/s in the positive x direction. Determine the final velocity in m/s.
