1. The problem statement, all variables and given/known data The rocket car is subjected to a constant acceleration of Ac = 6 m/s^2 until T1 = 15 s. The brakes are then applied which causes a deceleration at the rate shown until the car stops. Determine the maximum speed of the car and the time T when the car stops. 2. Relevant equations Area of Rectangle = L x W Area of a Triangle = 1/2(b)(h) 3. The attempt at a solution So I know that the area under the curve for an acceleration vs time graph would represent the velocity, but without having what the final time T was or what the final acceleration was, I'm not sure how to go about it. I know that at 15 seconds, the velocity is 90 m/s and that's about it. Any help would really be appreciated!
