Answer:

tangential speed ≈ 2.7 m/s

Step-by-step explanation:

formula: Vt = 2r / t

r = 3.5 m

t = 8.2 s

Vt = 2(3.5) / 8.2

Vt = 2.68184 m/s

Vt ≈ 2.7 m/s

correct on edge

~2.7 m/s. The circumference of the carousel, therefore the distance, is 22 meters, or 2 pi radius. Dividing that by the time will give you the velocity. Therefore, 22m / 8.2 seconds equals 2.7 m/s.
