During an auto accident, the vehicle's air bags deploy and slow down the passengers more gently than if they had hit the windshi
Marysya12 [62]

Answer: 0.28 m

Deceleration, a= -60 g

where g is the acceleration due to gravity=9.8 m/s^2

So, a= -60\times 9.8 m/s^2=-588 m/s^2

Using the equation of motion, we need to find the initial velocity,

v-u=at

final velocity, v=0

time, t= 31 ms=31\times 10^{-3}s

0-u=-588m/s^2\times 31\times 10^{-3} s=18.23 m/s

now, using third equation of motion,

s=ut+\frac{1}{2}at^2

we can find out the distance traveled by the person before coming to complete stop.

s=18.23m/s\times 31\times 10^{-3}s+\frac{1}{2}(-588 m/s^2) \times (31\times 10^{-3} s)^2=0.56 m-0.28 m=0.28 m
