Question

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.

Answer #1

kindly rate

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 rocket, initially at rest on the ground, accelerates straight
upward from rest with constant acceleration 34.3 m/s2 . The
acceleration period lasts for time 8.00 s until the fuel is
exhausted. After that, the rocket is in free fall. Find the maximum
height ymax reached by the rocket. Ignore air resistance and assume
a constant acceleration due to gravity equal to 9.80 m/s2 .

A rocket, initially at rest on the ground, accelerates straight
upward from rest with constant acceleration 39.2 m/s2 . The
acceleration period lasts for time 9.00 s until the fuel is
exhausted. After that, the rocket is in free fall.
Find the maximum height ymax reached by the rocket. Ignore air
resistance and assume a constant acceleration due to gravity equal
to 9.80 m/s2 .

A model rocket is fired straight up from the top of a 55-m-tall
building. The rocket has only enough fuel to burn for 3.0 s. But
while the rocket engine is burning fuel, it produces an upward
acceleration of 60 m/s2. After the fuel supply is exhausted, the
rocket is in free fall and just misses the edge of the building as
it falls back to the ground. Ignoring air resistance, calculate 1.

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?

A rocket is fired vertically upwards with constant acceleration
from the earth’s surface. After one
minute it reaches a height of 36 km, and the motor is shut off.
Neglect air resistance and variation
of g with height.
(a) Calculate the maximum height reached.
(b) Calculate the total time of flight.
(c) Draw a v − t diagram for the entire flight.

A kids rocket is fired from rest from the ground (y=0) at time
t1=0s. As the rocket fuel is burning its fuel it moves
vertically upward with constant acceleation of
+4.25m/s2. At t2=12s all fuel is used up and
rocket is in freefall and air resistance can be neglected in this
case.
what is the maximum height of rocket with respect to ground?
Also how long after being launched does the rocket return to the
ground? And what is the...

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.
Part A
What is the velocity of the rocket when it runs out of fuel?

launch a model rocket from ground level. it moves directly upward
with a constant acceleration of 66.5 m/s^2 for 1.20 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?

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?
