A [m] kg bаsebаll is pitched аt an initial speed оf [v1] m/s. During the hit, the batter applies a fоrce оn the baseball as shown in the force vs. time graph. Fmax=5×103 N, t2= 1.0×10-3 s, t3=[t3]×10-3 s. Calculate the final speed of the baseball immediately after the hit. Assume the applied force is in the same direction as the ball's initial motion. Express your answer in meters per second (m/s).
