Two children, Jason and Betsy, ride onthe same merry-go-round. Jason is a distance R from the axis ofrotation; Betsy is a distance 2R from the axis. (a) Is the rotationalperiod of Jason greater than, less than, or equal to the rotationalperiod of Betsy? (b) Choose the best explanation from among thefollowing:I. The period is greater for Jason because he moves more slowlythan Betsy.II. The period is greater for Betsy since she must go around a circle with a larger circumference.III. It takes the same amount of time for the merry-go-round tocomplete a revolution for all points on the merry-go-round.
