(a) A 19.0 kg child is riding a playground merry-go-round thatis rotating at 30.0 rev/min. What centripetal force (inN) must she exert to stay on if she is 2.00 m from itscenter? (Enter a number.)

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

(c) Compare each force with her weight. (For each answer, entera number.)

(force from (a))/(weight) =

(force from (b))/(weight) =
