A police car is moving to the right at 27 m/s, while a speeder is coming up from behind at a speed 38 m/s, both speeds being with respect to the ground. The police officer points a radar gun at the oncoming speeder. Assume that the electromagnetic wave emitted by the gun has a frequency of 4.3 x 109 Hz. Find the difference between the frequency of the wave that returns to the police car after reflecting from the speeder's car and the frequency emitted by the police car. -)))) police Vspeeder tal ( Number i Units +
