This is the question: A rocket is fired vertically upward with an initial velocity of 80 m/s. It accelerates upward at 4 m/s^2 until it reaches an altitude of 1000m. At that point, its engines fail and the rocket goes into free flight, with acceleration -9.80 m/s^2. Now this is what I want to know: Will 1000m be the maximum altitude the rocket reaches since the engines stop at that moment, or will the rocket continue on? I know that at the maximum altitude, the velocity has to be 0 m/s, but according to my calculations using the data given, I get the final velocity of 120 m/s at 1000m. Please help!
