KE Conservation & Rotation
DoNow: A 1.0 m diameter disk has 6.0 J of rotational energy when rotating at 3 m/s. Calculate the rotational inertia or moment of inertia for the disk. Calculate the mass of the disk. (notes)
AIM: I can describe kinetic energy of rotational systems and the conservation of energy in rotational systems.

I changed some of the values and questions for Amusing Rotations #2 for better continuity and so the v at the top of the ball return was non-negative. Take a look at the revised published version.
