The figure shows the path of a park ride that travels at constant speed through five circular arcs of radi Ro, 2Ro, and 3Ro. Rank the arcs according to the magnitude of the centripetal force on a rider traveling in the arcs, greatest first. If multiple arcs rank equally, use the same rank for each, then exclude the intermediate ranking (i.e. if objects A, B, and C must be ranked, and A and B must both be ranked first, the ranking would be A:1, B:1, C:3). If all arcs rank equally, rank each as '1'.
