A merry-go-round is spinning at a rate of 5 revolutions per minute. Cora is sitting 0.5 m from the center of the merry-go -round and Cameron is sitting right on the edge, 2.0 m from the center. What is the relationship between rotational speed of the two children?
a. Cameron's rotational speed is four times as much as Cora's rotational speedb. Cora's rotational speed is the same as Cameron's rotational speedc. Cora's rotational speed is four times as much as Cameron's rotational speedd. Cora's rotational speed is double Cameeron's rotational speede. Cameron's rotational speed is double Cora's rotational speed
