A child on a merrygoround is moving with a speed of 1.40 m/s when 1.18 m from the center of the merrygoround.
(a) Calculate the centripetal acceleration of the child. (and I got 1.08)
(b) Calculate the net horizontal force exerted on the child (mass = 25.0 kg).
(and I got 27.2)

Isnt acceleration= v^2/r ?
That does not give what you got.
