Sasha sits on a horse on a carousel 3.5 m from the center of the circle. She makes a revolution once every 8.2 seconds. What is Sasha's tangential speed?
O 0.9 m/s
O 1.3 m/s
O 2.7 m/s

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
