Acceleration Circular Motion question?
A Ferris Wheel makes a complete revolution every 20 seconds.
What is the speed of a rider on the edge of the Ferris Wheel if it has a radius of 5.0 meters?
How much centripetal acceleration is required to move the rider around the circle?

ω = 2π radians / 20s = π/10 rad/s ≈ 0.31 rad/s
speed at edge v = ωr = 0.31rad/s * 5.0m = 1.6 m/s ◄
centripetal a = ω²r = (0.31rad/s)²*5.0m = 0.49 m/s² ◄
