I have everything but E

Submarine A travels horizontally at 13.0 m/s through ocean water. It emits a sonar signal of frequency f = 5.22 103 Hz. in the forward direction. Submarine B is in front of submarine A and traveling at 4.5 m/s relative to the water in the same direction as submarine A. A crewman in submarine B uses his equipment to detect the sound waves ("pings") from submarine A. We wish to determine what is heard by the crewman in submarine B. Use the following equation.
f ' =

v + v0
v − vs

f
(a) An observer on which submarine detects a frequency f ' as described by the equation above?
Submarine ASubmarine B     [Correct: Your answer is correct.]
(b) In the equation above, should the sign of vS be positive or negative?
positive [Correct: Your answer is correct.]
(c) In the equation above, should the sign of vO be positive or negative?
negative     [Correct: Your answer is correct.]
(d) In the equation above, what speed of sound should be used?
1533 m/s [Correct: Your answer is correct.]
(e) Find the frequency of the sound detected by the crewman on submarine B. (Express your answer to four significant figures.)
(No Response) Hz

    A dolphin (Dolphin A) is swimming under the ocean at a speed of 4.87 m/s, emitting sonar sound wave at a frequency of 1222 Hz. The speed of sound waves under the ocean is 5518.8 km/h. Another dolphin (Dolphin B), located away is such that the two dolphins move towards each other. If Dolphin B is moving at 7.31 m/s, calculate the frequency that would be detected by a receiver attached to Dolphin B as the two fish swim towards...
