Question

Alcohol consumption slows people's reaction times. In a controlled government test, it takes a certain driver 0.320 s to hit the brakes in a crisis when unimpaired and 1.00 s when drunk. The car is initially traveling at 110.0 km/h. 1) How much farther does the car travel before coming to a stop when the person is drunk compared to sober

Answer 1

Answer:

$\triangle d=21.726m$

Explanation:

From the question we are told that:

Unimpaired time to hit break $t_i=0.320s$

Drunk time $t=1s$

Initial Velocity $v=110km/h$

Generally the equation for Average velocity is mathematically given by

$V_{avg}=\frac{\triangle d}{\triangle t}$

Therefore

$\triangle d=v.dt$

$\triangle d=31.95*(1-0.32)$

$\triangle d=21.726m$
