How much work is required to stop a 1000 kg car traveling at 100 km/hr?(adsbygoogle = window.adsbygoogle || []).push({});

What I was thinking was that I would use the formula for KE,

KE=1/2mv2 (last two of course is for squared

since the KE would equal work. I have gotten as far as:

KE= 1/2(1000 kg)(100km/hr)2

I am assuming that somewhere there is a conversion needed, I'm just not getting the next steps.
