Three objects (a solid sphere, a thin walled cylindrical ring, and a solid cylinder) are mounted on horizontal axles. They each have equal masses and radii. Weights are hung from strings wrapped around the axles (all the same radius) so that when the weights are dropped the objects rotate. Rank the three object as to their moment of inertias. Rank the three objects according to their acceleration.
A. sphere>ring>cylinder
B. ring>cylinder>sphere
C. cylinder>sphere>ring
D. sphere>cylinder>ring
E. ring>sphere>cylinder
