Building off of yesterday

The new Hummer 2 has 325 horsepower at 5200 rpm, 1 horsepower is 33000 foot-pounds/min. My baby is about a foot long and weighs about a pound. Thus a Hummer 2 has the required power to fully displace my baby 10,725,000 times in one minutes. Let the first displacement go up one foot from zero, then back down to zero, then down to negative one foot and then back to zero. this corresponds to 2,681,250 cycles per min. This translates into 44687.5 Hz, roughly the highest frequency you find in dog whistles.
