## Homework Statement

A crate is sitting on the back of a truck at 20 m/s with a μ of 0.4. With what acceleration can the truck stop without having the crate slide?

## Homework Equations

I'm not sure if I am supposed to use this equation:

a = μ(9.8)

## The Attempt at a Solution

a = 0.4(9.8) = 3.92 m/s^2.
