The state highway patrol radar guns use a frequency of 8.66 GHz. If you're approaching a speed trap driving 35.0 m/s, what frequency shift will your FuzzFoiler 2000 radar detector see

The frequency shift detected is

Explanation:

From the question we are told that

    The normal frequency of the state highway patrol radar guns

     The speed of approach is

Now the frequency measure by the the state highway patrol radar guns as your car approaches is mathematically represented as

Where c is the speed of light which a has constant value of

  Now

=>    

substituting values
