a car moving with a speed of 50 km/hr can be spotted by breaks after at least 6m.If the same car is moving with a speed of 100km/hr the minimum stopping distance is?
"Spotted by breaks"? Don't you mean "stopped by brakes"?
Stopping distance is proportional to V^2 if the deceleration rate is the same in both cases. That assumption is usually made. The stopping distance gets multiplied by 4 when the speed doubles.
