Q1. How many revolutions per minute would a 29 {rm m}-diameter Ferris wheel require to make for the passengers to feel "weightless" at topmost point?

Q2. A marching band consists of rows of musicians walking in straight, even lines. while a marching band performs in an event, such as a parade, and must round a curve in the road, the musician on the outside of the curve must walk around the curve in the same amount of time as the musician on the inside of the curve. This motion can be approximated by a disk rotating at a constant rate about an axis perpendicular to its plane. In this case, the axis of rotation is at the inside of the curve.
