# An automobile weighing 2000 kg, and going a speed of 60 km/hr, collides with a truck weighing 5 metric tons that was moving at right angles to the direction of the auto at a speed of 4 km/hr. If the two vehicles become joined in the collision, what is the magnitude and direction of their velocity after the collosion?
