Earlier today, I was talking with my friend about speed cameras measuring different speeds when moving.
This is the situation:
I am the red car and I'm driving
The green speed camera is getting pulled
50km/hby the blue car.
The speed camera is aimed at the left and measures my speed as I pass it.
My friend said that the camera would still measure
61km/h. I say the camera measures more (maybe
111km/h?) since how I understand, in relation to the camera, the red car moves faster than it moves in relation to the ground.
He couldn't give me an explanation of his theory, but he is sure.
Am I right or is my friend right? If he is, why is that?
Thank you for your help from us both.
