# Angular Kinematics

If you shrunk to the size of an ant, and were forced to live on the second hand of a wristwatch, it would behoove you to understand movement in a circle. Prepare for the worst with Angular Kinematics.

At the local swimming hole, a favorite trick is to run horizontally off a cliff that is \( 80 \text{ m} \) above the water, roll yourself up into a "ball", and rotate on the way down to the water. If the average angular speed of rotation is \( 2 \) revolutions per second, what is the total number of revolutions during the fall?

The air resistance is negligible, and the gravitational acceleration is \( g= 10 \text{ m/s}^2. \)
