1. The problem statement, all variables and given/known data Swati was driving her car over the speed limit when an oncoming car car flashes its lights warning her of a radar trap ahead. She decelerates from 39 m/s to 27 m/s in 6.0 s. What deceleration did her brakes apply? - im not sure what formula to use so does anyone have a clue what formula i could use for this question? Thanks for taking your time.
