Angular Momentum Shapes Ranking

APPH12-JM0M$H

You have four different objects. Thye each have the same radius, mass and angular velocity.

Rank the angular momentum of the four shapes from highest to lowest.

Object A: A spherical shell (hollow) spinning about an axis through its center of mass.

Object B: A solid sphere spinning about an axis through its center of mass.

Object C: A hoop spinning about an axis through its center of mass.

Object D: A solid disk spinning about an axis through its center of mass.

A

C > A = B > D
