Question 421415: An observer stands 46.0 m behind a marksmen practicing at a rifle range. The marksman fires the rifle horizontally which gives the speed of the bullet to be 985 m/s. How far does each bullet travel before the observer hears the report of the rifle? Assume that the bullet encounter no obstacles during this interval, and ignore both air resistance and vertical component of the bullet's motion. The speed of sound in air is 343 m/s.

An observer stands 46.0 m behind a marksmen practicing at a rifle range.
The marksman fires the rifle horizontally which gives the speed of the bullet to be 985 m/s.
How far does each bullet travel before the observer hears the report of the rifle?
Assume that the bullet encounter no obstacles during this interval, and ignore
both air resistance and vertical component of the bullet's motion.
The speed of sound in air is 343 m/s.
:
Find how long it takes the report to be heard 46 m away, then how far the bullet travels in that time;
46%2F343 * 985 = 132.1 meters
