# Ferris Wheel Part 2

A Ferris wheel with radius $$r$$ is rotating at constant angular speed $$\omega$$. The position of a passenger at the rim of the wheel may be described by a direction angle $$\theta$$:

• $$\theta = 0^\circ$$ at the right side of the wheel

• $$\theta = -90^\circ$$ at the bottom of the wheel

• $$\theta = +90^\circ$$ at the top of the wheel

Each passengers sits on a level (horizontal) seat. The coefficient of static friction between passenger and seat is $$\mu$$.

Which of the following equations describes the maximum angular speed for the Ferris wheel that allows the passengers to remain in their seats without additional support?
