1. The problem statement, all variables and given/known data A car accelerates from rest at 1.2 m/s^2 for a distance of 30 meters, after that it remains constant speed for 5 seconds, then it decelerates to a full stop in 4 seconds. 2. Relevant equations d=1/2at^2 v^2=v0^2+2a(x-x0) (x-x0)=Vot+1/2at^2 3. The attempt at a solution I tried using the above equation to figure out the total distance traveled since I am given acceleration, but I am not sure which time to use if not both and if the 30 meters and constant speed also has to be factored in. I tried using other kinematic equations with the the 30 meters and I read constant speed means velocity isn't changing so it's 0. Although I am still not getting the correct answer.
