1. The problem statement, all variables and given/known data A stuntwoman is preparing to take a punch, crash through a "candy glass" window, and fall a long distance. The script calls for her to emit a piercing scream just before she hits the "ground." In reality, she will land on a waiting airbag. Lights! Camera! Action! The primary camera crew, filming from her starting height, hears her last-instant scream at a frequency 3.77 kHz. Her scream has a frequency of 4.05 kHz when she is at rest. How far did she fall? Report this as a positive distance. 2. Relevant equations Fl=Fs(v-Vl/v+Vs) 3. The attempt at a solution I have easily found the speed of the girl falling to be 25.5m/s but I dont even know where to start as far as finding her distance. I have considered finding the wavelength but I dont know where to go from there. Do I need to you an echo equation for this? I've been looking at it for a solid 2 hours convinced I could figure it out but I'm about to the point where I need a little guidance. I dont need an answer I just need an idea of where to go from here. This isnt due for another 3 weeks but its driving me insane. THANKS!
