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.
(b) Calculate the net horizontal force exerted on the child (mass = 25.0 kg).

I will be happy to critique your work.

well for a) I got 1.08m/s^2
