## Homework Statement

2000Hz siren and worker are both at rest with respect to ground. What frequency does worker hear if the wind is blowing toward him from the siren at 12m/s?

## Homework Equations

f'=f(v/v-vs)

## The Attempt at a Solution

So since the worker is stationary, Vd in the numerator is 0. So the answer I got was:

2000*(343/(343-12)) = 2073Hz. Is this correct?
