A)They all have the same angular momentum.
B)The hollow cylinder has the most angular momentum.
C)The solid sphere has the most total kinetic energy.
D)The solid cylinder has the greatest rate of rotation.
E)They all have the same kinetic energy of rotation.

Question

Quizplus · Accepted Answer

The hollow cylinder has the largest moment of inertia among the three objects, which results in it having the most angular momentum when rolling at the same speed.
