It is possible for two objects of equal mass to have rotational masses because

B) The objects may be made out of different materials.
C) Rotational mass is always half the total mass.
D) An object not rotating has no rotational mass.

Question

Two objects with the same total mass can have different moments of inertia if their mass distributions are different.
