6.3 Centripetal Force 23. (a) A 22.0 kg child is riding a playground merry-go-round that is rotating at 40.0 rev/min. What centripetal force must she exert to stay on if she is 1.25 m from its center? (b) What centripetal force does she need to stay on an amusement park merry-go-round that rotates at 3.00 rev/min if she is 8.00 m from its center? (c) Compare each force with her weight.
A 22.0-kg child is riding a playground merry-go-round that is rotating at 50.0 rev/min. a. What centripetal force is exerted if he is 1.25 m from its center? b. What centripetal force is exerted if the merry-go-round rotates at 3.0 rev/min and he is 5.0 m from its center? c. Compare each force with his weight.

A 19.75 kg child is riding a playground merry-go-round that is rotating at 41.1 rev/min. What net force is acting on her if she is standing on the merry-go-round 1.15 m from its center in newtons? The net force in this situation is sometimes called "centripetal force". What net force (in N) is acting on her if she is standing on an amusement park merry-go-round that rotates at 2.2 rpm and she is 9.3 m from its center? How many...
A 15.0 kg child is riding a playground merry-go-round that is rotating at 40.0 rev/min. What centripetal force (in N) must she exert to stay on if she is 1.50 m from its center? N (b)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 6.00 m from its center? N (c)Compare each force with her weight. force from (a) weight = force from (b) weight =

A child is riding a merry-go-round that is turning at 7.18 rpm. If the child is standing 4.65 m from the center of the merry-go-round, how fast is the child moving?
A 50.0 kg child is on a 200.0 kg merry-go-round with a radius of 1.50 m. The child starts at 0.5 m from the center and moves to the edge. The child's parent accelerates the merry-go-round from rest at 0.75Td to a speed of 1.5 Fad How long did the parent push the merry-go-round? How much force is required to hold the child when at 0.5 m from the center? (This centripetal force could be from friction, holding on, or...
