Acoustic Measurement of Potato Cannon Velocity
Courtney, Michael; Courtney, Amy
Physics Teacher, v45 n8 p496-497 Nov 2007
Potato cannon velocity can be measured with a digitized microphone signal. A microphone is attached to the potato cannon muzzle, and a potato is fired at an aluminum target about 10 m away. Flight time can be determined from the acoustic waveform by subtracting the time in the barrel and time for sound to return from the target. The potato velocity is simply flight distance divided by flight time.
