# Find minimum stopping distance

## 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?

F=ma

## 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

You want to know the final velocity of a truck that is coming to a stop?

I tried that but it doesn’t get me the right answer

Never Mind, you’re right .
I did a mistake in my calculations
Thanks !
