Suppose that a police car on the highway is moving to theright at 27 m/s, while the speeder is coming up from behind at aspeed of 39 m/s, both speeds being with respect to the ground.Assume that the electromagnetic wave emitted by the radar gun has afrequency of 8 x 10^9 Hz.
a) Find the magnitude of the differencebetween the frequency of the emitted wave and the wave that returnsto the police car after reflecting from the speeder's car.
b) Which wave has the greater frequency?
