Question

A hunter who is standing 220.0-m away fires his rifle. How long (in seconds) will it take the sound to travel to your ear.

Answer 1

Answer:

t = 1.52 s

Explanation:

The speed of sound is constant and depends only on the properties of the medium in which the sound propagates, many of these properties change with temperature, in the case of propagation in air, the speed of sound

          v =$331 \ \sqrt{1+ \frac{T}{273} }$

where the temperature is in degrees centigrade

         v = 331 $\sqrt{1+ \frac{6}{273} }$ = 331    1.0109

         v = 334.6 m / s

let's use the uniform motion relationships

         v = x / t

          t = v / x

let's calculate

          t = 334.6 / 220.0

          t = 1.52 s
