Can sum1 help me answer this sat physics q?

<p>A carpenter hammers at a rate of 1 hammer per sec. After he stops hammering, you hear two more blows.
How is it possible for someone to hear sound after it looks like a carpenter has stopped hammering? How far away is he from you? assume STP </p>

<p>im jw is this related to the doppler effect or echoes?</p>

<p>no, the point of this is that the speed of sound is slower than that of light. To solve this, you do d=(speed of light - speed of sound)(2 hammers)</p>

<p>whast the 2 hammers part?</p>

<p>bump bump help plz :)</p>

<p>Bumpppp :)</p>

<p>This is related to the phenomenon during storms. You see lightning before you hear thunder. That’s because, although both occur at the same time, thunder (sound) travels at a slower speed so the sound waves arrive at you with a slight delay.</p>

<p>right, speed of light is def faster than speed of sound
but is there a formula to calculate the distance “How far away is he from you? assume STP”</p>

<p>would it b speed of sound x 2 sec which is like 662meters?</p>

<p>Yeah, that’s correct.</p>

<p>sweet thanks :)</p>
