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)...
