How High Can This Rocket Go After The Engines Shut Off?

A rocket accelerates straight up from rest for 20 seconds20~\mbox{seconds} with an acceleration of 8 m/s28~\mbox{m/s}^2. After 20 seconds20~\mbox{seconds} the rocket motor shuts off and the rocket continues to coast upwards. How high does the rocket go in meters?

Details and assumptions

  • You may take the acceleration of gravity as 9.8 m/s2-9.8~\mbox{m/s}^2.
  • You may neglect air resistance.
