8. Centripetal Forces & Gravitation
Uniform Circular Motion
27PRACTICE PROBLEM
In the diagram provided below, a small ball with mass (m) is confined to move within a vertical cylindrical disc of radius (r), which rotates about a vertical axis at a frequency (f). Is it feasible for the ball to reach the height of the center of the circle (θ = 90°)? Consider the inner surface of the disc is frictionless.
