You have designed a rocket to be used to sample the local atmosphere for pollution. it is fired vertically with a constant upward acceleration of 19 m/s2. after 20 s, the engine shuts off and the rocket continues rising (in freefall) for a while. (neglect any effects due to air resistance.) the rocket eventually stops rising and then falls back to the ground. you want to get a sample of air that is 14 km above the ground. (a) what is the highest point your rocket reaches?
