Compute the second moment of inertia around the z-axis (the second monment of inertia is denoted by /o in the textbook; also denoted by i, in section 15.6) for: 1. spinning a frisbee (in x-y plane and around the z-axis) with radius r and mass density δ around its center (think of spinning the frisbee on the tip of your index finger). 2. spinning the same frisbee around a point on its edge (this time your index finger is touching a fixed point on the edge of the frisbee but rotation is still around the z-axis) hint: in both cases, take the origin to be the tip of your index finger; so, rotation is around the z axis in both cases.
