Suppose a clay model of a koala bear has a mass of 0.215 kg and slides on ice at a speed of 0.745 m/s. It runs into another clay model, which is initially motionless and has a mass of 0.340 kg. Both being soft clay, they naturally stick together. What is their final velocity (in m/s)? (Enter the magnitude.). m/s
