**Steve**, Tuesday, October 11, 2011 at 3:42pmso, the only thing to calculate is the time to fall.

Multiply that by 5.5 to get the revs.

Hmmm. How about the old s = 1/2 at^2

Sloppy language. The center of mass is a point, and cannot be horizontal. Assume the velocity is horizontal, so there is no initial vertical component.

And watch out for those rocks at the bottom of the cliff!!! That's where the horizontal velocity comes in. :-)

And, the water better be shallow. At 5.5rev/s you'll be too dizzy to swim when you hit!
