Physics Help: Calculating Breaking Distance with -9000 N Force

[emma123]

hi this is my first year in physics and i am already confused on it. I really need help on the following question: "The force of -9000 N is used to stop a 1500 kg car traveling at 30 m/s. What is the breaking distance is needed to bring the car to a halt?" I have no idea which formula to use or where to begin since i don't have the time or acceleration. Please help me. Thanks!

You have a force and a mass, you can find teh acceleration using Newton's 2nd law.

you already have "v", once you find "a" you can use one of those kinematic equations to find "d".
