a rocket rises vertically from rest, with an acceleration of 3.2 m/s(s) until it runs out of fuel at an altitude of 845 m. After this point, its acceleration is that of gravity, downward. what is the velocity when the rocket runs out of fuel? how long does it take to reach that point? what is the maximum altitude and how long to reach it? what is the velocity when it strikes earth? how long is the rocket in the air?

A model rocket is fired vertically upward from rest. Its
acceleration for the first three seconds is given by a(t) = 60t
ft/s2 , at which time the fuel is exhausted and it becomes a freely
“falling” body and falls to the ground.
(a) Determine the position function s(t) for all times t >
0.
(b) What is the maximum height achieved by the rocket? (
c) At what value of t does the rocket land?

A model rocket is fired vertically upward from rest. Its
acceleration for the first three seconds is a(t)=96t, at which time
the fuel is exhausted and it becomes a freely "falling" body. 1919
seconds later, the rocket's parachute opens, and the (downward)
velocity slows linearly to −16 ft/s in 5 s. The rocket then
"floats" to the ground at that rate.
(a) Determine the position function s and the velocity function
v(for all times t).
v(t)=

A rocket is fired straight upward, starting from rest with an
acceleration of
25.0 m/s2. It runs out of fuel at the end of 4.00 s and
continues to coast
upward, reaching a maximum height before falling back to Earth.

rocket’s height when it runs out of fuel; (b) find the rocket’s
velocity when it
runs out of fuel; (c) find the maximum height the rocket
reaches; (d) find the
rocket’s velocity the instant before the rocket...

A 7400 kg rocket blasts off vertically from the launch pad with
a constant upward acceleration of 2.15 m/s2 and feels no
appreciable air resistance. When it has reached a height of 550 m ,
its engines suddenly fail so that the only force acting on it is
now gravity. a)What is the maximum height this rocket will reach
above the launch pad? b)How much time after engine failure will
elapse before the rocket comes crashing down to the launch...
