## Homework Statement

A test of the prototype of a new automobile

shows that the minimum distance for a con-

trolled stop from 100 km/h to zero is 41 m.

Find the acceleration, assuming it to be

constant as a fraction of the free-fall accel-

eration. The acceleration due to gravity is

9.81 m/s2.

Answer in units of g.

## Homework Equations

Kinematics equations

## The Attempt at a Solution

I'm actually unsure how to even begin this problem. The statement has me confused, such as what they mean by "a fraction of the free-fall acceleration."
