### How fast is the speeder going

Assignment Help Physics
##### Reference no: EM13319267

A police car is moving at 37.1 m/s (83.0 mi/h) behind a speeding car that is going faster. The speed limit is 29.1 m/s (65.0 mi/h). A police car radar "clocks" the speed of the other car by emitting microwaves with frequency 2.9 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 1358 s-1. How fast is the speeder going.
