Suppose a child is riding on a merry-go-round at a distance about halfway between its center and edge. She has a lunch box resting on wax paper, so that there is very little friction between it and the merry-go-round. Which path shown in the sketch will the lunch box take when she lets go? The lunch box leaves a trail in the dust or the merry-go-round. Is that trail straight, curved to the left, or curved to the right? Explain your answer.
