# A tricky game of catch

**Classical Mechanics**Level 4

You and a friend are going to ride on a Ferris wheel. For a little extra fun, when your friend is at the very top of the Ferris wheel she's going to drop a tennis ball. How far around the Ferris wheel **in radians** from your friend should you sit so you can catch the ball?

**Details and assumptions**

- The Ferris wheel radius is \(R=20~\mbox{m}\).
- The Ferris wheel goes around at a constant angular velocity \(\omega=0.2~\mbox{rad/s}\).
- The acceleration of gravity is \(-9.8~\mbox{m/s}^2\).
- Neglect air resistance.
