Calculating Acceleration of a Car After Braking

[QUOTE="IDespisePhysics, post: 4982825, member: 539375"] [h2]Homework Statement [/h2] A car is traveling at 95 km/hr. The driver steps on the brakes and the car comes to a stop in 60 meters. What is the car's acceleration? [h2]Homework Equations[/h2] My issue might be which formula is correct but, I believe I would use, vf^2=vi^2+2ax [h2]The Attempt at a Solution[/h2] Every time I begin any problem I write down the givens. d= 60 meters Vi= 95 km/hr Vf= 0 m/s Are my givens wrong? If not, I've continued to plug it in into the problem above. I assume I'm using Kinematics and since the other equations require 't' or time, I don't believe I use those equations for this problem. As I plug the givens into the equation above, the math doesn't add up to the answer my teacher had said it was; which is -5.81m/s^2. [/QUOTE]
