Centripetal Acceleration

Question 3 • [HSPHY] Physics Sem 1 (26-27)

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?

Answer
A
0.9 m/s
B
1.3 m/s
C
2.7 m/s

Explanation

Tangential speed is the distance traveled in one revolution divided by the time for that revolution. Sasha travels one circumference, 2π(3.5 m) ≈ 22.0 m, in 8.2 s, so her speed is about 22.0 ÷ 8.2 ≈ 2.7 m/s. The correct choice is 2.7 m/s.
