(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

While sledding down a hill Jenny(40kg with the sled) reaches a top speed of 6m/s at the bottom. She then slides on flat ground to a stop. If the coefficient of friction between the sled and the ground is 0.04 how far will Jenny slide?

2. Relevant equations

V_{F}^{2}=V_{I}^{2}+2a[tex]\Delta[/tex]X

([tex]\Delta[/tex]X=total distance)

V_{F}=V_{I}+at

F_{N}=mg

F_{F}=F_{N}U

3. The attempt at a solution

I have found F_{N}and got 392(F_{N}=mg, or F_{N}=(-40kg)(-9.8)=392) then found the total frictional force that was 15.68(F_{F}=F_{N}U, or F_{F}=(392)(.04)=15.68) I'm having problems finding the acceleration, so i can actually find the distance, how can i take the info i have now and plug it into an equation to find acceleration? If i need a different equation than i have there, please show me, i'm confused on what to do next
