Answer to Question #19206 in Mechanics | Relativity for archie
A police car is moving at 29 m/sand is behind a speeding car moving faster in the same direction as the police car. The radar gun in the police car emits an 8.0x109 Hz electromagnetic wave. The frequency of the returning wave is measured to be 318Hz less than the emitted frequency. Find the speeder's speed.
z=(318/2) Hz / (8.0*10^9 Hz) = 2*10^(-8) z=v/c v=c*z = 3*10^8 m/s * 2 * 10^(-8) = 6 m/s speedingcar has velocity 6m/s bigger then police car. Hence, speeding car has velocity 29+6 = 35 m/s
I'm not good at math in general and I knew I would automatically fail the class, so then I looked online to find me some help and I found assignment expert. They were very friendly and helped me get through my course. I already have started to recommend assignment expert to other students. I highly recommend assignment expert!
