Question

Describe the forces acting on a child riding a horse on a merry go round. Which of these forces provides the centripetal acceleration of the child?

Answer 1

There are several forces over the kid, one is done by the machine to move the child over the horse

Also, thanks to the circular movement you get a centripetal force and acceleration, pointing to the center of the game.

And as a reaction to it you get a force done by the game against the centripetal force, so the child is not going to the center
