## Homework Statement

A crate is being transported on a flatbed truck. The coefficient of static friction between the crate and the bed is 0.470. What is the minimum stopping distance if the truck, traveling at 70 km/h, is to decelerate uniformly and the crate is not to slide forward on the bed?

## Homework Equations

F=ma

Vi^2 - Vo^2 = 2ad

## The Attempt at a Solution

I found the acceleration ,

Fnet=ma

Us•mg=ma (The mass basically cancels out here)

Us•g = a

4.606 = a To find the distance, I figured to use Vi^2 - Vo^2 = 2ad , due to not having time . However , how do you find the final velocity of the initial velocity is 70 km/h .

I’m stumped here
