Unlock Stopping distance
How far does the bus travel before it comes to a stop?
Stopping distance = reaction distance + braking distance. Reaction distance = v · t_R, braking distance = v² / (2·a). Double the speed and the braking distance quadruples. Reaction time and deceleration are assumptions (dry/wet/icy) — hence an estimate.
