    ~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.

    Answer:

    tangential speed ≈ 2.7 m/s

    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
