Wrong Rotational Inertia Formula
5. Derive a formula which can be used to describe the rotational inertia of the earth around an axis going through its center of mass. I = 1/12 m(a² + b²) NO!
A handwritten physics response gives the rectangular-plate moment of inertia formula for a question asking about Earth’s rotational inertia, then emphatically writes “NO!” The joke is the student recognizing that the formula is inappropriate for Earth and rejecting their own answer.
