Do 2-4 A baseball and a basketball are placed initially at rest at the top of a 5 meter high ramp that makes an angleof 13° with the horizontal. They are released and roll without slipping to the bottom.1. Without calculation, predict which would reach the bottom first. Explain how you reachedsion (what is the key difference between the basketball and baseball here?)yourconclu-2. What is the linear speed v of each of the balls when they reach the bottom?3. How long does it take each of the balls to reach the bottom?4. What is the total kinetic energy of each of the balls at the bottom?
