Physics - Sound Wave Question with Solution | TestHub

A bus is moving with a velocity vB along positive x -axis along a road as shown in the figure. A shooter S is at a distance $\ell$ from the road. He has a detector which can detect signals only of frequency 1500 Hz . The bus blows horn of frequency 1000 Hz . When detector detects a signal, shooter immediately shoots towards the road along SC and bullet hits the bus. If velocity of sound in medium is $360\mathrm{m}/\mathrm{s}$ and $\frac{{\mathrm{V}}_{\text{bus }}}{{\mathrm{V}}_{\text{sound }}}=\frac{2}{3\sqrt{3}}$, then velocity of bullet is $(12{)}^{\mathrm{n}}\mathrm{m}/\mathrm{s}$, Find n .
