This should be easy...the problem asks for the amount of work needed to stop a 1000kg car traveling @ 100km/h.(adsbygoogle = window.adsbygoogle || []).push({});

I am having a hard time do to the fact acceleration,distance nor time is given.

here is how I think i need to approach this:

convert 1000km/h to m/sec

find acceleration

use Work=Mas*acceleration*Distance to find work

Here are the variables i know:

Mas=100kg

Vf = 0

V0 = 27.78 m/s

how can i find acceleration if no distance or time is given? I would think i need to find acceleration to calculate work needed to stop.

any hints?
