Question

A rocket rises vertically, from rest, with an acceleration of
4.0 m/s^{2} 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?

Answer #1

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.
1) What is the velocity of the rocket when it runs out of
fuel?
2) How long does it take to reach this point?
3) What maximum altitude does the rocket reach?
4) How much time (total) does it take to reach maximum
altitude?

A rocket rises vertically, from rest, with an acceleration of
3.2 m/s2 until it runs out of fuel at an altitude of 715 m . After
this point, its acceleration is that of gravity, downward.

A rocket is fired from its launch pad with
acceleration 9.0
m/s2.
The
rocket
travels vertically upward for 13.0 s at which time
all the fuel is burned
out.
Calculate the total time the rocket is in the air, from launch to
falling
back to the
ground.

A model rocket is fired vertically from the ground with a
constant acceleration of 35.7 m/s2 for 1.71 s at which time its
fuel is exhausted. What is the maximum height (in m) reached by the
rocket? Round your answer to 3 significant figures.

You launch a model rocket from ground level. It moves directly
upward with a constant acceleration of 73.0 m/s2 for
1.35 seconds, at which point it runs out of fuel. Assuming air
resistance on the rocket is negligible, what is the maximum
altitude (above the ground) achieved by the rocket?
m

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?

2. A rocket blasts off vertically from the launch pad with a
constant upward acceleration of 2.25 m/s^2 and feels no air
resistance. When it has reached a height of 525 m, its engines
suddenly fail so that the only force acting on it is now
gravity.
a) How fast is the rocket traveling when the engine fails?
b)What is the maximum height the rocket will reach above the launch
pad? c) How much time after engine failure will elapse...

A rocket blasts off vertically from rest on the launch pad with
a constant upward acceleration of 2.90 m/s2 m / s 2 . At 20.0 s s
after blastoff, the engines suddenly fail, and the rocket begins
free fall.
Find the magnitude of the rocket's velocity at its highest
point.
Find the magnitude of the rocket's acceleration at its highest
point.

A model rocket rises with constant acceleration to a height of
3.1 m, at which point its speed is 28.0 m/s.
a. How much time does it take for the rocket to reach this
height?
b. What was the magnitude of the rocket's acceleration?
c. Find the height of the rocket 0.10 s after launch.
d. Find the speed of the rocket 0.10 s after launch.

A small rocket is launched vertically from the ground and
experiences an upward acceleration of 5 m/s2. The engine burns out
after 4 seconds and the rocket moves under the influence of gravity
until it returns to the ground. You may neglect air resistance.
Draw the position, velocity, and acceleration vs. time curves for
the entire flight from t=0 to t=9.5 s. Take the +y axis to be
upward.
A) what is the Position vs. Time graph?
B) What is...
