Alcohol consumption slows people's reaction times. In a controlled government test, it takes a certain driver t1=0.31 s to hit the brakes in a crisis when unimpaired and t2=0.93 s when drunk. If the car is initially traveling at v=89 km/h, what additional distance Δx does the car travel before the brakes are applied when the person is drunk than it travels when the person is sober? Δx= ?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

Given data:
Initial velocity of car (v) = 89 km/h
Reaction time when driver is sober (t1) = 0.31 s
Reaction time when driver is drunk (t2) = 0.93 s
Required:
The additional distance traveled before applying brakes when the person is drunk
