A child on a merry-go-round is moving with a speed of 1.40 m/s when 1.18 m from the center of the merry-go-round.

(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)

1 answer

Isnt acceleration= v^2/r ?

That does not give what you got.
