Two children ride on a merry-go-round, with child 1 at a greater distance from the axis ofrotation than child 2, as shown in our sketch. (a) Is the angular speed of child 1 greater than,less than, or the same as the angular speed of child 2? (b) Which of the following is the bestexplanation for your prediction?I. Child 1 is moving faster than child 2, and hence has the greater angular speed.II. Child 2 is closer to the axis of rotation, which results in a greater angular speed.III. Both children complete a revolution in the same time, so their angular speeds are the same.

Question
Two children ride on a merry-go-round, with child 1 at a greater distance from the axis of
rotation than child 2, as shown in our sketch. (a) Is the angular speed of child 1 greater than,
less than, or the same as the angular speed of child 2? (b) Which of the following is the best
explanation for your prediction?
I. Child 1 is moving faster than child 2, and hence has the greater angular speed.
II. Child 2 is closer to the axis of rotation, which results in a greater angular speed.
III. Both children complete a revolution in the same time, so their angular speeds are the same.
