This should be easy...the problem asks for the amount of work needed to stop a 1000kg car traveling @ 100km/h.
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?
