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.
4. A child sitting 2 meters from the center of a merry-go-round moves at a speed of 2 m/s. Calculate (A) the centripetal acceleration of the child and (B) the horizontal force exe child (mass 22.5 kg). (A) 1 m/s2 b. 2 m/s2 c. 3 m/s2 d. 4 m/s2 e. 5 m/s2 a. 22.5 N b. 45 N c. 67.5 N d. 90N e. 112.5 N 5. If Earth was moved to a new orbit that was twice as far...
