One rainy day, a car with a mass of 1 250 kg moving at 20.0 m/s hits the rear end of another car with a mass of 1 610 kg moving at 8.0 m/s in the same direction. What is the final velocity of the two cars if they stick

together? What is the change in kinetic energy of the system? What type of collision occurred in the system?​
