Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have a problem where I honestly have no idea how to get started. I have a slight idea what might be invloved but other than that, I am stumped.

Here's the problem: At the local swimming hole, a favorite trick is to run horizontally off a cliff that is 8.6m 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 1.4 rev/s. Ignore air resistance and determine the number of revolutions she makes while on the way down.

What's throwing me is that there is a height involved and none of the examples provided in my book or from my professor for that matter included a problem with height. I think I read somewhere however that d = s but again, I don't understand how to work this. I know I will have to use one of the Rotational Kinematic equations, but like I said this is about all I know.

Thanks for any help provided.
