A rocket rises vertically, from rest, with an acceleration of 4.0 m/s2 until it runs out of fuel at an altitude of 1200 m . After this point, its acceleration is that of gravity, downward.

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 the rocket strike the Earth?

f. How long (total) is it in the air?

A rocket is launched vertically up with no initial velocity. Propulsion is provided by the ejection of mass with constant velocity of ejection u = 66.0 m/s relative to the rocket and at a constant rate so determined that the initial acceleration is zero. The mass of fuel that can be ejected is 55.0% of the total mass at launch. Assuming constant gravitational acceleration, how long does it take the rocket to achieve maximum upward acceleration?
