Final answer:
The velocity of the riders on the Whirligig ride is approximately 2.51 m/s.
Step-by-step explanation:
The velocity of the riders on the Whirligig ride can be determined using the formula v = 2πr/T, where v is the velocity, r is the radius of the circle, and T is the time taken to complete one revolution. In this case, the radius is 6.11 m and the time is 4.85 seconds. Plugging in these values, we get:
v = (2π * 6.11) / 4.85 ≈ 2.51 m/s
Therefore, the velocity of the riders on the Whirligig ride is approximately 2.51 m/s.
