    i dont 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.

    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?
