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"?
5 kinematic equations
The Attempt at a Solution
I was using this : Δd→=Vf→Δt-0.5a→Δt2
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?
