Sorry but I missed one question in my inbox. It came from someone named ‘Johnny Nine’. Apparently he thinks “Ask Fitz” is actually “Stump Fitz”. He sent me the following:
A person sees a heavy stone strike the concrete pavement. A moment later two sounds are heard from the impact: one travels in the air and the other in the concrete, and they are 1.07s apart. How far away did the impact occur? Take the speed of sound in concrete as 2.95×103 m/s and give your answer in km.
Mr. Nine, do I look like a guy that likes to solve math riddles? Does anyone like to solve math riddles? If so should those people be beaten to within an inch of their life, nursed back to health and then shot in the fucking head? Yes they should. Are you one of those people? I hope not.
On a more serious note if I was walking in the street and a rock hit the pavement in front of me I would not be listening for the sound. I would either be running my ass off or picking it up and throwing it back at someone.
