The drawing shows three objects rotating about a vertical axis. The mass of each object is given in terms of m0, and its perpendicular distance from the axis is specified in terms of r0. Rank the three objects according to their moments of inertia, largest to smallest.

Answer 1

moment of inertia for each mass is
mr^2

compute each, then rank them. Goodness.

Answer 2

The answer is A, then C, then B

Answer 3

wtf, bobpursley is absolutely correct; moreover, it's simple af to just solve through using the formula bob gave, bunch of idiots only wants answers instead of learning
