A bullet shot from a gun travels at a constant speed of 330 m/s towards a target that is 35 m away. The gunshot was loud, registering an intensity level of 71.4 dB at the location of the target. a) What reaches the target first: the sound of the gunshot or the bullet itself? Why? *b) Assuming the sound from the shot travels -unimpeded- uniformly in all directions, and that there is no interference from any other sound, what is the furthest distance the shot can be heard?
