## Homework Statement

Determine the average number of g's experienced by someone abruptly coming to rest from an initial velocity of 30mph (such as in a car crash). Take the distance involved in coming to rest to be 1 m.

## Homework Equations

V=Vo+at

ΔS=VoT+1/2at^2

V^2=Vo^2+2aΔS

## The Attempt at a Solution

t=?

a=?

Vo= 30 mph

V=?

ΔS=?

Thank you, I'm really stuck and any help will be deeply appreciate it.
