Thanks Alan and Nauseated.
I now get that the radar will have to clock the oncoming car at a smaller speed then what the car is really travelling at.
Each of your pics gave me different info and they both helped a lot .
Alan I can see that your pic gives me the desired answer but I can't quite fathom why the pic is right. ![]()
I am still contemplating the actual maths of it. Is it possible for you to show me mathematically, with the units, why your answer is correct?
Why is the triangle drawn like that? Why is the right angle at the police car ?
Is that to seperate the x and y components of the velocity relative to the police car? Maybe there is a glimmer of understanding coming. ![]()
Maybe I just need to think about it for a bit ? (´・_・`)
