1. The problem statement, all variables and given/known data You are driving your car and you heavily apply the brakes for a period of 2.1 seconds. The car keeps moving for a distance of 14.6m before it completely stops. What is the acceleration (in m/s2) experienced by the car? Is it truly "acceleration"? 2. Relevant equations 5 kinematic equations 3. The attempt at a solution I was using this : Δd→=Vf→Δt-0.5a→Δt2 14.6=0(2.1)-0.5a→(2.12) 14.6= 0-0.5a→(4.41) I don't know what to do after that, I don't know what to do with the part of the equation with the acceleration. Am I even using the right kinematic equation?
