A police car is moving at 39.6 m/s to catch up with a speeder directly ahead. The speed limit is 29.1 m/s. A police car radar “clocks” the speed of the other car by emitting microwaves with frequency 6.10 × 1010 Hz and observing the frequency of the reflected wave. The reflected wave, when combined with the outgoing wave, produces beats at a rate of 1400 s−1. If the speeder is going faster than the police car, how fast would it have to go so that the reflected microwaves produce the same number of beats per second?
