Uniformly Accelerated Linear Motion (JavaScript example)

Uniformly Accelerated Linear Motion - Example

Interactive computation - requires JavaScript enabled - Mathematical explanation

Two identical cars A and B travel in the same direction. Being faster, B overtakes A.

Just when the cars are side by side, an obstacle appears. After a short reaction time, both drivers brake.

If the car A hit the obstacle at a given speed, what would have been the speed of the car B when hitting the same obstacle?

Drivers' reaction time

Braking efficiency

	Car A			Car B

Initial speed		km/h			km/h
Impact speed		km/h			km/h

Impact distance			m
Impact time		s			s
Distance covered before braking		m			m
Braking distance		m			m

Legend

Car braking capability expressed in percentage of g (terrestrial attraction).
This parameter is ignored when the drivers' reaction time is set to 0
Impact distance & time from initial sight of the obstacle
Distance covered before actually braking (brain reaction time)
Braking distance from when the brakes are effectively activated
