At the local swimming hole, a favorite trick is to run horizontally off a cliff that is 8.3m above the water.  One diver runs off the ede of the cliff, tucks into a "ball" and rotates on the way down with an average angular speed of 1.6 rev/s.  Ignore air resistance and determine the number of revolutions she makes while on the way down.
