A rocket rises vertically, from rest, with an acceleration of 3.2 m/s2m/s2 until it runs out of fuel at an altitude of 800 mm . After this point, its acceleration is that of gravity, downward   What maximum altitude does the rocket reach?   How much time (total) does it take to reach maximum altitude?   With what velocity does it strike the Earth?
