(a) What are the speed and period of a person on a carousel if the person has a centripetal acceleration with a magnitude of 1.0 m/s2 when she is standing 3.0 m from the axis?

(b) What is the magnitude of her centripetal acceleration if she then moves in to a distance of 1.5 m from the axis while the carousel continues to spin at the same rate?
