Final answer:
The minimum use zone between a merry-go-round and a spring rocker is determined by the radius of the merry-go-round and the distance traveled by the child on the spring rocker. To calculate the minimum use zone, you would add the radius of the merry-go-round to the distance traveled by the child. For example, if the radius of the merry-go-round is 4.0 m and the child on the spring rocker travels 0.75 m from the axis of rotation, the minimum use zone would be 4.75 m.
Explanation:
The minimum use zone between a merry-go-round and a spring rocker is the distance required to ensure the safety of the children on both play structures. This zone is determined by the potential danger of collision between the two moving objects. To calculate the minimum use zone, we need to consider the radius of the merry-go-round and the distance traveled by the child on the spring rocker.
For example, if the radius of the merry-go-round is 4.0 m and the child on the spring rocker travels 0.75 m from the axis of rotation, the minimum use zone would be the sum of these distances, which is 4.0 m + 0.75 m = 4.75 m.
Therefore, to ensure safe use, there should be a minimum distance of 4.75 meters between the merry-go-round and the spring rocker.
