Applying Skills Use the illustration showing a collision between two balls to answer Questions 23-25. Before After 2 m/s 0 m/s 0.5 m/s 1.5 m/s orb 23. Calculating Use the formula for momentum to find the momentum of each ball before and after the collision. Assume the mass of each ball is 0.4 kg. A 24. Inferring Find the total momentum before and after collision. Is the law of conservation of momentum satisfied in this collision? Explain. 25. Designing Experiments Design an experiment in which you could show that momentum is not conserved between the balls when friction is strong.
