Question

Passengers on a carnival ride move at constant speed in a horizontal circle of radius

5.0 m, making a complete circle in 4.0 s. What is their acceleration?
​

Answer 1

Answer:

12.3 m/sec^2

Explanation:

Circumference of the circle =2πr

=2×3.14×5=31.4m

velocity=7.85m/s

Acceleration, a = v^2/r

=12.3 m/sec^2
