Homework Help: Physics

Posted by Allie on Saturday, August 13, 2011 at 2:34pm.

Clap your hands and estimate the energy and power released as sound waves.

I know Kinetic energy= 1/2*m*v^2
and Power is KE/t

but how do I find the velocity of the sound wave made from clapping my hands?
and for the mass do I use the mass of my hands?
thanks
