A 2011kg car is moving at a velocity of 23.9m/s, east. Suddenly, it collides with a second car on an icy surface that has a mass of 1950kg and is moving at a velocity of 15.7m/s, east. During the collision, the two cars stick together and continue to move. What is the final velocity of the two cars? What type of a collision is this?
