A police car is moving at 38m/sec to catchup with a speeder directly ahead. The speed limit is 29.1 m/sec. Police car radar clocks the speed of other car by by emmitting microwave radiation of frequency 3E10 Hz and observing frequency of reflected wave. The reflected wave when combined with outgoing wave produces beat at rate of 1400 sec^-1. How fast is speeder going?
