## Homework Statement

A car is traveling at 60.0mph when it collides with a stonewall. The car comes to rest after the first foot of the car is crushed. What was the average horizontal force acting on a 150lb driver while the car came to rest?

## Homework Equations

I'm not a hundred percent sure which equations to use but, I searched through questions I've had in the past and found an example however, it deals with distance.

vf^2=vi^2+2ax

SIGMA F= MA

## The Attempt at a Solution

Again, I wasn't quite sure where to even start so, I decided to find acceleration because I thought it might be important with SIGMA F=MA. I've listed the givens which, may or may not be correct.

Vi = 60MPH ---> 88 FT Per Second

Vf = 0 m/s

m = 150lbs
