A 23.0 kg child is riding a playground merry-go-round that is rotating at 45.0 rev/min. What centripetal force (in N) must she exert to stay on if she is 2.00 m from its center?

What centripetal force (in N) does she need to stay on an amusement park merry-go-round that rotates at 3.00 rev/min if she is 5.00 m from its center?

Compare each force with her weight. (For each answer, enter a number.)
(force from (a))/(weight) =
(force from (b))/(weight) =
