Asked by Allie
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

Estimate the energy in your moving hands and assume it all goes to sound energy.
m = mass of one hand
v = speed of one hand
energy = 2 (1/2) m v^2
m = mass of one hand
v = speed of one hand
energy = 2 (1/2) m v^2
