A boxcar of mass 3.21 x 104 kg is rolling south at 5.08 m/s when it collides and couples with another boxcar of mass 5.18 x 104 kg that is rolling north at 2.38 m/s. What is the velocity of the coupled boxcars after collision? Take north as positive and express your result to three significant digits.
