## Homework Statement

Submarine is traveling at 12 m/s toward an aircraft carrier emits a 2400 Hz sonar pulse. The reflected pulse returns with a frequency 2310 Hz.

What is the speed of the aircraft carrier?

(Positive/negative means the carrier is moving toward/away from the submarine.) The speed of sound in water is 1500 m/s.

## Homework Equations

-C-Vair/-C-Vsub*Freq1ofSub = Freq1ofAircraft

C - Vsub/C - Vair*Freq2ofair = Freq2ofSub

## The Attempt at a Solution

Im not sure how to solve the problem using those equations
