a 1200kg car is travelling at 35 m/s. When the brakes are applied, a braking force of 3200N is applied to the car until the car comes to rest. How far does the automobile travel over the time it is decelerating?

Do you have multiple choice, or are you asked to answer yourself?

Okay. @AllTehMaffs is busy right now so I'll try and answer this; it'll be good practice for the test anyway.

ok thanks. what grade are you in??

First, we have all the given information:
$$m=1200kg$$$$V_0=35 m/s$$$$f=3200N$$
I'm assuming that even though it's saying "a braking force is applied", it's going in the other direction... It should be okay to think of it as friction.

(hint hint - the velocity isn't a force, so isn't in the free body ^_^)

=.= @AllTehMaffs I knew that, I just put it in there for convenience...
But I scribbled it out for you anyway|dw:1384671543231:dw|
