    1. The problem statement, all variables and given/known data

    A car is traveling at = 24 . The driver applies the brakes and the car decelerates at = -4.0 . What is the stopping distance?

    2. Relevant equations

    3. The attempt at a solution

    i just started my physics class and I have a horible teacher, i have never taken physics before and i think i just need a push in the right direction!

    You know the initial velocity, final velocity, and acceleration. Which formula has these 3 knowns as well as displacement (which is unknown, obviously)?

    For the future you should write the unit

    Hi minifhncc! :smile:

    Please don't answer other members' questions for them …

    especially when they haven't had time to reply to previous help (rmax58 is probably still asleep).

    In this forum, we try to minimise the help, so that members can work the problems out themselves, and learn better.

    And stop trying to re-interpret the questions … as you yourself said …​
