Question:medium
If a source of sound initially at rest is moving away from a stationery observer with an acceleration of $11~ms^{-2}$, then the time taken for the frequency of sound heard by the observer to become 10% less than the frequency of source is (Speed of sound in air $=330~ms^{-1}$)}
If a source of sound initially at rest is moving away from a stationery observer with an acceleration of $11~ms^{-2}$, then the time taken for the frequency of sound heard by the observer to become 10% less than the frequency of source is (Speed of sound in air $=330~ms^{-1}$)}
Show Hint
Always convert Doppler shift into velocity first, then apply kinematics.

A source of sound S emitting waves of frequency 100Hz and an observer O are located at some distance from each other. The source is moving with a speed of 19.4m s⁻1 at an angle of 60^∘ with the source–observer line as shown in the figure. The observer is at rest. Find the apparent frequency observed by the observer. (Velocity of sound in air =330m s⁻1).
