Hello everyone!
I was just wondering that while driving, is there a way to calculate speed of an other car that passes you?
I worked out a way but I needed more heads on this [that's what she..meh] so here's it:
When the car traveling faster than me goes pass me(me - carA;other car - carB), I fix a stationary point (pointA) ahead of carB on the road (like a tree). Now when carB passes that pointA, I start counting. I keep counting till I myself (CarA) reaches that pointA and note down the value (say x). Now while still counting I again fix another point (pointB) ahead of CarB and note down the value (say y) when it reaches there. Finally I note down the value (say z) when I (CarA) reach that pointB.
From this CarB's speed turns out to be ((z-x)/(y-1)) times my speed.
Now there's a lotta assumptions here because I wanted an "easy" method.
That was my take, could there be other methods (perhaps better than this)?
