A rocket rises vertically, from rest, with
an acceleration of 3.2 m/s2 until it runs out of fuel at an altitude
of 950 m. After this point, its acceleration is that of gravity, down ward. (a)
What is the velocity of the rocket when it runs out of fuel? (b) How long does
it take to reach this point? (c) What maximum altitude does the rocket reach?
(d) How much time (total) does it take to reach maximum altitude? (e) With what
velocity does it strike the Earth? (f) How long (total) is it in the air?
