SUMMARY

The discussion focuses on calculating the distance to a target based on the time it takes for the sound of a bullet striking the target to reach the shooter. The bullet's muzzle speed is 170 m/s, and the sound speed, calculated using the formula Vc=331+(0.6*T) with a temperature of 72°F (22.2°C), is 344.32 m/s. The total time from firing to hearing the impact is 1.30 seconds. The equation 170x + 344.32(1.3 - x) = D is established to find the distance to the target, where x represents the time taken by the bullet to reach the target.

PREREQUISITES
  • Understanding of basic physics concepts related to projectile motion.
  • Familiarity with the speed of sound calculations in air.
  • Knowledge of algebraic equations and solving for variables.
  • Ability to convert temperature from Fahrenheit to Celsius.
NEXT STEPS
  • Learn how to derive the speed of sound in different mediums.
  • Study projectile motion equations and their applications.
  • Explore the effects of temperature on sound speed in air.
  • Practice solving real-world physics problems involving time, distance, and speed.
USEFUL FOR

Students studying physics, educators teaching projectile motion, and anyone interested in practical applications of sound and motion calculations.

Homework Statement



A person holds a rifle horizontally and fires at a target. The bullet has a muzzle speed of 170 m/s, and the person hears the bullet strike the target 1.30 s after firing it. The air temperature is 72°F. What is the distance to the target?

Homework Equations


Vc=331+(0.6*T)
Vc= speed of sound through dry air (m/s)
T= temperature(Degrees C)



The Attempt at a Solution


Vc=331+(0.6*22.2)=344.32m/s
170x+344.32(1.3-x)=D

One more condition: the bullet has to travel exactly as far in getting to the target as the sound does in traveling back.
 
Thank you. Got it
