1.) In the example of the cannons at USMA from the speed of sound content in this module, the source (cannon) and the observer (me) were stationary. Let us assume the wavelength of the sound the cannon made was 1.302m. Consider three observers that are 1200km away from the cannons on that day: Observer A: stationary Observer B: in a vehicle moving with speed 20.00 m/s directly away from the cannon Observer C: in a vehicle moving with speed 20.00 m/s directly toward the cannon What time passes between the firing of the cannon and the arrival of its sound at the position of observer A? 2.) In the example of the cannons at USMA from the speed of sound content in this module, the source (cannon) and the observer (me) were stationary. Let us assume the wavelength of the sound the cannon made was 1.710m. Consider three observers that are 1.200km away from the cannons on that day: Observer A: stationary Observer B: in a vehicle moving with speed 21.37 m/s directly away from the cannon Observer C: in a vehicle moving with speed 21.37 m/s directly toward the cannon Calculate the frequency of the cannon's sound
