15 points) Submarine sonar cannot only locate another ship nearby. It can also tell how fast it is going. Sub A at all stopped emits a sonar pulse in a burst of 850 Hz sound. The pulse reflects off the hull of another submarine, sub B which is moving along a course that is in line with sub A. The returning frequencyis higher andbeats against the original pulse with a beat frequency of 2.5 Hz. How fast is the sub B moving
