A boy and a girl are riding on a merry-go-round that is turning. The boy is twice as far as the girl from the merry-go-round's center. If the boy and girl are of equal mass, which statement is true about the boy's moment of inertia with respect to the axis of rotation?
A) His moment of inertia is 4 times the girl's.
B) His moment of inertia is twice the girl's.
C) The moment of inertia is the same for both.
D) The boy has a greater moment of inertia, but it is impossible to say exactly how much more.
E) The boy has a smaller moment of inertia, but it is impossible to say exactly how much
