Answer:
The correct option is C
Explanation:
From the question we are told that 
   The initial speed of the rocket is  
     The speed of the rocket engine sound is 
     The final speed of the rocket is  
The speed of the sound at  would still remain V this because the speed of sound wave is constant and is not dependent on the speed of the observer(The mountain ) or the speed of the source (The rocket ).
 would still remain V this because the speed of sound wave is constant and is not dependent on the speed of the observer(The mountain ) or the speed of the source (The rocket ).
   A clear example when  lightning strikes you will first see (that is because it travels at  the speed of light which is greater than the speed of sound) but it would take some time before you hear the sound of the  
lightning
Here we see that the speed of the lightning(speed of sound) does not affect the speed of the sound it generates  
 
        
             
        
        
        
Vf^2 = Vi^2 + 2ad
a= 34 m/s^2
Vi = 0 m/s
d = 3400m
Vf = 480.83 m/s
a=v/t
t=v/a
t=480.83/34
t=14.142 s
