Suppose that a police car on the highway is moving to the right at28 m/s, while a speeder is coming up from almost directly behind ata speed of 38 m/s, both speeds being with respect to the ground.The police officer aims a radar gun at the speeder. Assume that theelectromagnetic wave emitted by the radar gun has a frequency of7.00 109 Hz. Find the the difference between the frequency of thewave that returns to the police car after reflecting from thespeeder's car, and the original frequency emitted by the policecar.
This is what I have so far: (sqrt(3E8-10 - 10)/(3E8+10 + 10)) x 7E9
