Submarine A is chasing submarine B at a depth of 250 m. Submarine A is travelling at a speed of 10 while submarine B is travelling faster at a speed of 12". Submarine B sends out a sonar ping at 1 kHz. Assume that the speed of sound at this depth is 1200. a) What frequency of sound hits submarine A? (Answer:982 Hz) b) What would the frequency be if submarine B was moving at double its speed? (Answer:972 Hz)
