Asked by tristan
At 10 degrees C a cannon fires a shell at 1324m/s
a) how fast is the shell traveling relative to the soundwave of the explosion?
b) how far away from the cannon is the observer how sees the shell pass by 2s before the sound of the explosion arrives?
I don't understand a and I think that you need some info from a to solve b. So I'm a little bit lost.
Thank you for your help (:
