A source \( (S) \) emitting sound of frequency \( f_{0}=960 \mathrm{~Hz} \) is projected with velocity \( 10 \sqrt{2} \mathrm{~ms}^{-1} \) at an angle \( \theta=45^{\circ} \) with the horizontal. Simultaneously, a detector \( (O) \) is projected vertically upwards with a speed \( 10 \mathrm{~ms}^{-1} \). There is no wind and speed of sound in air is \( 310 \mathrm{~ms}^{-1} \). After the source and detector fall to the ground, they come to rest. (Take, \( g=10 \mathrm{~ms}^{-2} \) )https://bit.ly/YTAI_PWAP https://www.pw.live
