1. The problem statement, all variables and given/known data Alright, the problem might be somewhere in the translation, or maybe I'm missing something, but anyway, here it is, word for word: You push a pot from the edge of your balcony, which is d = 20.0 m above the ground. The pot falls towards an unsuspecting man, whose height is h = 1.75 m, and who's standing right below. Hypothesize that the man needs Δt = 0.300 s to react to any warning. How close to the ground can the pot get , so that there can be enough time for the man to react, after hearing the warning from the balcony? https://email@example.com/service.svc/s/GetFileAttachment?id=AQMkADAwATYwMAItYWVhZi1kMjdjLTAwAi0wMAoARgAAA5PfTv0SpppHr3yc003kVrgHAAH04A%2BJ7mRGmo%2BChKo3rFcAAAIBDAAAAAH04A%2BJ7mRGmo%2BChKo3rFcAAAB9OvcPAAAAARIAEACdhkV8uS0rS7vLr%2BuftI%2FE&X-OWA-CANARY=JRgD1tYNR0617ZNb8HMQwzAt2HSebNQY4Ewkle7GAjlw1KRK4scHujEaSeZxy80AsL_pHn0p6F8.&token=7c2f7d89-bfdc-4a20-a40e-9fd19b213e35&owa=outlook.live.com&isc=1&isImagePreview=True 2. Relevant equations V = Δx/Δt V = 343 m/s 3. The attempt at a solution Dunno, really. When I glansed at it, I figured it'd give me the mass, angle, initial velocities and whatnot, and it'd be a mix of an horizontal shot, and a sound wave exercise. But nope, none of that. This doesn't specify whether it's a free fall or horizontal shot, so I guess it doesn't matter, and we're just meant to focus on the sound part of it. Thing is, maybe it's the translation, but I'm not sure what those "0.3s" are, exactly. Is it the time it takes him to react after hearing something? That's what I thought. So I went ahead and found how much time it'd take the sound from us/me to arrive to his ears: V = (d-h)/tw <=> 343 m/s = (20.0-1.75) m/tw <=> tw = 0.0532 s I don't have anything else though. I'm probably missing something, but time is short, so I could really use any help I can get. Thanks a ton! PS: This can be found in the Sound Waves chapter btw.
