Question

A rocket is launched from rest and moves in a straight line at 70.0 degrees above the horizontal with an acceleration of 30.0 ?/?2m/s2. After 25.0 ?s of powered flight, the engines shut off and the rocket follows a parabolic path back to earth.

1- Find the time of flight from launch to impact.

2- What is the maximum altitude reached?

3- What is the horizontal distance between the launch pad and the
impact point?

Answer #1

A rocket is launched from rest and moves in a straight line at
72.0° above the horizontal with a constant acceleration of 47.8
m/s2. After 31.7 s the engines shut
off and the rocket follows a parabolic trajectory back to the
ground (Assume that the acceleration due to gravity is 9.81
m/s2). What is the time of flight from launch
to impact?
What is the maximum altitude reached?
What is the horizontal distance reached?

A rocket is launched at an angle of 53.0° above the horizontal
with an initial speed of 104 m/s. The rocket moves for 3.00 s along
its initial line of motion with an acceleration of 32.0
m/s2. At this time, its engines fail and the rocket
proceeds to move as a projectile.(a) Find the maximum altitude
reached by the rocket.(b) Find its total time of flight.(c) Find
its horizontal range. Please solve with steps thanks!

A rocket blasts off vertically from rest on the launch pad with
a constant upward acceleration of 2.30 m/s2 . At 20.0 s after
blastoff, the engines suddenly fail, and the rocket begins free
fall.
How long after it was launched will the rocket fall back to the
launch pad?

A rocket is launched at an angle of θ = 51° above the horizontal
with an initial speed vi = 55 m/s, as shown below. It moves for 25
s along its initial line of motion wth an acceleration of 20.4
m/s2. At this time, its engines fail and the rocket proceeds to
move as a free body.
(a) What is the rocket's maximum altitude? m
(b) What is the rocket's total time of flight? s
(c) What is the...

A rocket ship leaves the launch past at rest and accelerates at
a rate of 15 m/s2 for 30 seconds. At this point, the engines fail,
and the rocket continues under the influence of gravity for several
more seconds. What is the maximum height reached by the rocket in
meters? How long will the rocket in the previous problem be in
flight, from the moment that it launches to the moment that it
crashes back into the launch pad? Give...

A model rocket is launched straight upward with an initial speed
of 59.0 m/s. It accelerates with a constant upward acceleration of
2.50 m/s2 until its engines stop at an altitude of 160
m.
(a) What can you say about the motion of the rocket after its
engines stop?
(b) What is the maximum height reached by the rocket?
(c) How long after liftoff does the rocket reach its maximum
height?
(d) How long is the rocket in the air?

A model rocket is launched straight up with a speed of
45.0 m/s and maintains an upward acceleration, including air and
gravitational resistance. the acceleration of the rocket
is 800m/s2 for 10s at which point the engines
run out of fuel. The rocket continues upward to its maximum height
and falls back towards the Earth. After falling for 7.65m, from its
maximum height, what is the decay of the rocket reaching its
starting point.

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.

During launches, rockets often discard unneeded parts. A certain
rocket starts from rest on the launch pad and accelerates upward at
a steady 3.10 m/s2 . When it is 235 m above the launch pad, it
discards a used fuel canister by simply disconnecting it. Once it
is disconnected, the only force acting on the canister is gravity
(air resistance can be ignored). How high is the rocket when the
canister hits the launch pad, assuming that the rocket does...

4. A model rocket is launched upward from rest with an upward
acceleration of 11.0 ?Τ? 2 . The rocket booster propels the rocket
for 6.00s before cutting out. The rocket then free-falls back to
the ground. a. Solve for the maximum height reached by the rocket.
(ans: 420m) b. Solve for the velocity of the rocket right before it
strikes the ground. (ans: −90.7 ?Τ?) c. Solve for the total time
the rocket was in the air before hitting...
