- A dog sits at the center of a disk that is rotating at a constant rate. The dog slowly moves to the edge of the disk. Which of the following values doesn't change? Angular velocity Rotational inertia Rotational Kinetic Energy Angular momentumQuestion 1A hollow cylinder (hoop), a solid cylinder (disk), and a solid sphere, each of mass M and radius R, roll down a hill of height h. Rank the objects based on their total kinetic energy at the bottom of the hill. Rank the one with the most energy 1, etc. If two are equal, give them the same ranking. hoop___________ disk_______________sphere_______________Justify your ranking
