Two men standing close to a long straight metal pipe and at some distance from each other . One man fires a gun and the other hears two explosions ,with a time interval of one second between them . If the velocity of sound in metal is 3630m/s and in aur is 330 m/s , the distance between two men is ?
Verified Answer
Two men standing close to a long straight metal pipe and at some dista...
Let the velocity of sound=v m/s
Let velocity of air=u m/s
Distance between A and B = xm
In first case :
Resultant velocity of sound= u+v

Speed= Distance/ time
(v+u)=x/t1 --(1)

In second case :
Resultant velocity= v-u
Speed = Distance/time
v-u=x/t2-----(2)
Solving equation 1 and 2 we get :
2v=(x/t1+x/t2)
v=x/2[1/t1+1/t2]
From equation 1 and 2 we get :
u=x/t1 - v
=x/t1-x/2t1-x/2t2
=x/2t1-x/2t2
=x/2[ 1/t1-1/t2]
Velocity of sound in  air v = x/2 [1/t1+1/t2] and
velocity of wind/air =u=x/2[1/t1-1/t2]
