Study Notes
Problem Scenario
- A train is traveling, and rifles are fired at a point along the train's path.
- A man on the train hears two rifle sounds with a time difference of 11 minutes and 45 seconds.
Calculations
- Speed of sound: 330 m/s
- Time difference between rifle sounds: 11 minutes and 45 seconds = 705 seconds ( conversion of time difference to seconds)
- Train speed: 72 km/h (given when the man heard the second sound)
Distance and Time Relationships
- The distance the train travels from the place where the rifles were fired to the man who heard the second sound is unknown and can be calculated.
- The time difference between the two rifle sounds can be calculated using the speed of sound.
- The distance between the two rifle sound sources is unknown and can be calculated.
