SUMMARY
The frequency of a child's swing motion is determined by the time it takes to complete a full cycle. In this case, the swing takes 3 seconds to go from maximum velocity to minimum velocity, indicating that the full cycle duration is 6 seconds. Therefore, the frequency is calculated as 1/6 Hz, which is equivalent to approximately 167 mHz. The correct answer is B. 170 mHz, as it is the closest option to the calculated frequency.
