Question

At the local swimming hole, a favorite trick is to run horizontally off a cliff that is 6.53 m above the water. One diver runs off the edge of the cliff, tucks into a "ball," and rotates on the way down with an average angular speed of 1.99 rev/s. Ignore air resistance and determine the number of revolutions she makes while on the way down.

Step 1

According to the vertical kinematics equation,

Step 2

Substitute 0 for *v _{y}*

Step 3

Substitute the ...
