Help with physics, speed of sound?

SUMMARY

The discussion focuses on calculating the air temperature based on the speed of sound using the formula v = 332 + 0.6T. Given that the observer is 2 km away and hears each chop after 2 seconds, the speed of sound is determined to be 1 km/s. The calculation leads to a temperature of 1113.3°C, although the physical validity of the scenario is questioned. Participants confirm the correctness of the equation and suggest ensuring proper unit usage in the final answer.

PREREQUISITES
  • Understanding of the speed of sound formula v = 332 + 0.6T
  • Basic knowledge of distance, time, and speed calculations
  • Familiarity with unit conversion and temperature measurement
  • Ability to analyze physical scenarios for realism
NEXT STEPS
  • Review the physics of sound propagation in different mediums
  • Learn about temperature measurement units and conversions
  • Explore real-world applications of the speed of sound in various environments
  • Investigate the implications of theoretical versus practical physics scenarios
USEFUL FOR

Students studying physics, educators teaching sound properties, and anyone interested in the practical applications of temperature calculations in acoustics.

Homework Statement


You see a neighbour in a cottage across the lake chopping wood. He is 2 km away and you see that it takes 2 s to hear each chop after you see it happen. Calculate the air temperature. (v= 332+ 0.6 T)


Homework Equations



v=d/t

The Attempt at a Solution


v= 1 km/s
0.6 T= 668 m/s
T= 1113.3 ?

With the numbers you have here, that would appear to be correct. Make sure that you include units on your Temperature for your solution. The equation you're using works and your logic is good. Double check your distances and times in the problem, as the problem doesn't seem "physical" as is, but if the distance is 2km and it is 2s difference, yes, you have the correct answer.
