Q2

Consider a ferris wheel that has a diameter of 250 m and a revolution period of about 30

minutes. You are riding the wheel with a bucket of water and are making careful measurements

of the shape of the surface of the water as a function of time.

Sketch the shape of the water surface at the four points indicated in the figure, indicating the

values of all relevant angles.

How fast would the ferris wheel have to rotate for a passenger to feel weightless at the top of

the wheel?
