hey friend
see when sound dies then at that time engine is switched off ..
so distance travelled in 30 sec.
distance (d) = speed of sound × time
= 320 × 30 = 9600 m
let velocity of helicopter when engine is switched off be v
initial velocity = 0
v^2 = u^2 +2as
v^2 = 0 + 2×3×9600
=) v = √57600
=) v = 240 m/s
