A) A merry-go-round at a children's park begins at rest and is pushed by a parent while a child holds onto the ride at the outer edge, 3.10 m from the center. The parent pushes with a constant force for 2.74 s until the child is moving with a speed of 11.0 m/s. What is the magnitude of the net acceleration on the child the instant before the parent stops pushing the merry-go-round? (Give your answer to at least one decimal place.)
