Final Answer:
The ride at the carnival has a radius of 15 meters.
Step-by-step explanation:
The ride described resembles a Ferris wheel with four spokes radiating from a central point. Given that each spoke is 15 meters long, this indicates the radius of the Ferris wheel.
In a circular motion, the distance from the center to any point on the circumference is termed as the radius. For this ride, the length of each spoke, 15 meters, represents the radius since the spokes extend from the central point to the outer pods where passengers sit.
Therefore, the radius of the ride, equal to the length of each spoke, is 15 meters.
Understanding the radius is crucial for calculating various aspects of circular motion, such as the circumference, velocity, or centripetal force, which are vital in determining the ride's dynamics and safety measures.
