Problem
A merry-go-round in a playground is a circular platform of radius 4.0m. It takes 6.0s to complete one full rotation when running at a steady rate.
(a) Determine the frequency of rotation.
(b) Calculate the centripetal acceleration of a child standing on the rim.
(c) If the radius of the platform were doubled while the time period remained the same, what would be the new centripetal acceleration? Justify your answer quantitatively.
