Suppose a clay model of a koala bear has a mass of 0.200 kg and slides on ice at a speed of 0.750 m/s. It runs into another clay model, which is initially motionless and has a mass of 0.350 kg. Both being soft clay, they naturally stick together. What is their final velocity?

Step-by-step solution: In this problem we have to calculate the final velocity of a clay model koala bear initially moving with a different velocity and now it runs into another clay model, which is initially motionless and has a mass so,using the given data find their final velocity respectively: Step 1 of 3 The relation between masses of each clay model and velocity after sticking together is Here is the mass of first clay model, is the mass of second clay model, is the velocity of first clay model, is the velocity of second clay model, and v is the final velocity.
