3. During maneuvers in the northern Pacific Ocean, two attack submarines are heading straight for each other on a collision course. The first sub is traveling at 30 km/hr, while the second submarine is traveling at 75 km/hr. The first sub sends out a sonar pulse of 1000 Hz which is picked up by the second sub. What is the frequency of the sonar pulse detected by the second sub? The speed of sound in sea water is 1520 m/s. v, = 30 km/hr v, = 75 km/hr
