Expert Witnesses Use Physics to Analyze Radar Speed Testimony in Court Case

  • Thread starter uicha
  • Start date
In summary, the conversation discusses conflicting testimony in a court case where a police officer claims a car was traveling at 176 km/h based on radar readings, while the driver argues they were only going 88 km/h. Expert witnesses are needed to use physics to justify both positions and visual aids will be used as evidence. The possibility of the Doppler formula being used is brought up, but the person is not familiar with it and asks if there is another way to solve the problem.

i don't know how to solve it so i need for your help to solve the problem below..thanks
There is conflicting testimony in a court case. a police officer claims that his radar monitor indicated that a car was traveling at 176 km/h(110mi/h). The driver argues that the radar must have recorded the relative velocity because he was only going 88 km/h (55 mi/h). Is it possible that both are telling the truth? could one be lying? prepare scripts for expert witnesses, for both the procecution and the defense, that use physics to justify their positions before the jury. create visual aids to be used as evidence to support the different arguments.

thankyou but I'm not learning about doppler formula yet, so i can't use this fomular to solve it...do you have other way to solve? thanks

Suppose the police car and the suspect's car were heading toward each other at 55 mph. What speed would you expect the radar gun in the police car to indicate?
