Angular and linear speed
A Ferris wheel at a carnival has a diameter of 16 meters. Suppose a passenger is traveling at 9 kilometers per hour. (A useful fact: =1km1000m.)(a) Find the angular speed of the wheel in radians per minute.(b) Find the number of revolutions the wheel makes per hour. (Assume the wheel does not stop.)Do not round any intermediate computations, and round your answer to the nearest whole number.

Sáenz-Ludlow, Bailey & Athanasopoulou What to Know About Functions Angular Velocity&Linear Velocity 3. In 2008, the old Ferris wheel at the world famous Santa Monica piere in Santa Monica, California, was replaced with a new solar powered Ferris wheel that contains thousands of energy efficient LED (light-emitting diode) lights that can illuminate into many different colors and deisgns. The wheel is approximately 85 feet in diameter and rotates 2.5 revolutions per minute. Find the linear velocity (in mph) of the...

This is in regarding centripetal force (university physics 1): The London Eye Ferris wheel has a diameter of 120 m and rotates at 2 revolutions per hour. This is so slow that any change in perceived normal force is minimal. However, you decide it is your destiny to help tourists experience physics, so you increase its speed to 2 rpm (revolutions per minute). a) By what percentage does a passenger feel heavier than normal weight at the very bottom? b)...
