1. The problem statement, all variables and given/known data In coming to a stop the acceleration of a car is given as a= -4t. If it is traveling at 32m/s when the brakes are applied, how far does is travel while stopping? 3. The attempt at a solution 1.) Integrate acceleration to find velocity as a function of time v= -2t^2 + C1 at t=0 , v = 32m/s v = -2t^2 + 32 2.) Integrate velocity to find displacement as a funtion of time s = (2/3)(t^3) + 32t + C2. This is where I get stuck. Is it correct to assume that at t=0 , s will be zero and therefore C2 is zero?
