A rocket is launched straight up. It contains two stages (Stage 1 and Stage 2) of solid rocket fuel that are designed to burn for 10.0 and 5.0 s, respectively, with no time interval between them. In Stage 1, the rocket fuel provides a net upward acceleration of 18 m/s2. In Stage 2, the net upward acceleration is 13 m/s2. Neglecting air resistance, calculate the maximum altitude above the surface of Earth of the payload and the time required for it to return back to the surface.

A 1000 kg weather rocket is launched straight up. The rocket
motor provides a constant acceleration for 16 s, then the motor
stops. The rocket altitude 20 s after launch is 3600 m. You can
ignore any effects of air resistance. What was the rocket's
acceleration during the first 16 s?

PLEASE ANSWER PARTS A, B, C, D, AND E.
A rocket is launched straight up with a constant acceleration of
25 m/s2. Six seconds after liftoff, a bolt falls off the side of
the rocket.
(a) Determine the velocity of the bolt just before it falls off
the side of the rocket.
(b) Determine the altitude of the bolt (measured from the
ground) just before it falls off the side of the rocket.
(c) How long is the bolt in...

(1 point) A rocket is launched from rest and moves in a straight
line at 25.0 degrees above the horizontal with an acceleration of
70.0 ?/?^2. After 35.0 s of powered flight, the engines shut off
and the rocket follows a parabolic path back to earth.
a)Find the time of flight from launch to impact. HINT: Simple
projectile motion after engines are shut down.
HINT: Do not forget to include the engine-on time in your time
calculation.
b)What is the...

1. A model rocket is launched straight upward with an
initial space of 50.0 m/s. It accelerates with constant upward
acceleration of 2.00 m/s^2 until its engines stop at an altitude of
150m. (a) how long does it take for the engines to stop? (b) what
is the velocity of the rocket when its engine stop? (c) draw a
graph for acceleration versus time (be careful to label your axis
correctly). (d) what is the maximum height reached by the...

In the first stage of a two-stage rocket, the rocket is fired
from the launch pad starting from rest but with a constant
acceleration of 3.50 m/s2 upward. At 25.0 s after launch, the
second stage fires for 10.0 s, which boosts the rocket’s velocity
to 132.5 m/s upward at 35.0 s after launch. This firing uses up all
the fuel, however, so after the second stage has finished firing,
the only force acting on the rocket is gravity. Air...

In the first stage of a two-stage
rocket, the rocket is fired from the launch pad starting from rest
but with a constant acceleration of 3.50 m/s2 upward. At 25.0 s
after launch, the second stage fires for 10.0 s, which boosts the
rocket�s velocity to 132.5 m/s upward at 35.0 s after launch. This
firing uses up all the fuel, however, so after the second stage has
finished firing, the only force acting on the rocket is gravity.

A rocket is launched from rest and moves in a straight line at
65.0 degrees angle above the horizontal with an acceleration of
42.0m/s square. After 32.0 s of powered flight, the engines shut
off and the rocket follows a parabolic path back to Earth. Find the
time of flight from launching to impact. What is the maximum
altitude reached? What is the distance from launch pad to
impactpoint? Ignore the variation in g with height

A model rocket is launched straight upward with an initial speed
of 42.0 m/s. It accelerates with a constant upward acceleration of
2.50 m/s2 until its engines stop at an altitude of 160
m.

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 upward with an innitial speed of
11.0 m/s. it accelerates with a constant upward acceleration of 22
m/s^2 until its engines stop 3.0 seconds later. it then continues
on as a free fall particle until it hits the ground.
(a) draw and label a diagram of the above and below
information
(b) find the velocity (in m/s ) of the rocket at the instant
it runs out if fuel.
(c)find the max height (in...

A rocket is launched straight into the air with initial
velocity 200 ft/s. Assume the launch is instantaneous. How high
will it go, and how long will that take (use time increments of
0.01 seconds)? G= - 32.2 ft/s2 , H0=0 (the
ground)
V(t)=V0 + g t
H(t)= H0 + V0 t + ½ g t2
The rocket deploys a parachute after 9 seconds and descends at a
constant rate of 20 ft/sec. How long does it take to reach...
