What should be the initial velocity of a rocket if it to hit a target 1000 km away?
initial velocity would be ZERO before launch. To calculate the velocity you would need to hit that target at that distance you would need to know the mass of the rocket and the angle of launch or trajectory simplifying it
How did you explain conservation of momentum when a rocket ship takes off?
Momentum P of a body with mass m and velocity v is given by:P = m∙vNewton's first law of motion establishes conservation of momentum on abody as long as there is no net force applied on it.Let's assume our Rocket Ship is about to be launched from the surface ofa planet with no gravity force, so we can leave out the influence of thisforce from the discussion.At time t ≤ 0 from launch, the Rocket Ship's velocity v is zero, and soits momentum P is also zero.When the Rocket Ship starts his motion upwards, the initial system (theRocket Ship), is now conformed by two subsystems: The Rocket Ship goingup and the exhaust gases being sent down.To give a simple view of what happens, lets assume that the massof the exhaust gases is expelled at a constant velocity vg through the wholeprocess till the Rocket Ship's engine stops. Then the final condition ofmomentum would be:P = mR∙vR + mg∙vg = 0where mR and mg are the final Rocket Ship's mass and the total mass ofexhaust gases expelled respectively, and vR the Rocket Ship's final velocity.You have to realize that the vectors of velocity VR and Vg will have oppositesigns.If we now would want to include the planets gravity force, this willbe affecting the momentum of the Rocket Ship by producing an accelerationin the opposite direction of its velocity. If we now think of the originalsituation of Rocket Ship and planet at rest, when the Rocket Ship ispushing away from the planet the gravitational attraction between theRocket Ship and planet works both ways. And so the lose of momentumby the Rocket Ship because of the gravitational force is compensated bythe planets lose of momentum in the opposite direction !.
What is the energy source a rocket?
momentum
What is the force that accelerates a rocket called?
The combustion of rocket fuel ejects a mass of material at high velocity. In accordance with Newton's third law, the momentum of the ejecta generates an equal and opposite reaction - which propels the rocket forward.
Can an object have momentum in space?
Yes. Momentum is based entirely upon mass and velocity, as shown by the equation p=mv, where p is momentum, m is mass, and v is velocity. Since an object can still have both mass and velocity in space, it can have momentum in space.
How does a rocket travel?
By expelling hot gasses extremely fast from the rocket nozzle. Due to the conservation of momentum, expelling mass at high velocity causes the rocket to gain momentum and therefore velocity.
What is the Momentum of a water rocket with the weight od 1185.5ml?
Momentum is mass times velocity. Without knowing the speed of the rocket, momentum cannot be calculated.

Rocket works on the principle of conservation of?
linear momentum. A rocket works by expelling gases from one end at a very high velocity. The escaping gases have a very high speed and this with their mass translates to a very large momentum. Due to the principle of conservation of momentum the body of the rocket is pushed forward. If both the momentum of the gases as well as that of the rocket are added the sum is zero.
How fast will the rocket go if you were traveling to the moon?
Destination does not affect velocity.
How is it possible for a rocket to propel itself through space?
This is possible via the conservation of momentum. A rocket ejects matter from its back and this matter carries momentum. To conserve momentum the rocket must gain an equal amount of momentum in the opposite direction. Since momentum is related to velocity this causes the rocket to move. This is basically an application of Newton's third law. You might have been confused with the situation in air. For example an airplane moves through air by pushing air past it (using its propeller). This accelerates the air, and thus increases its momentum. The airplane must therefore gain momentum in the opposite direction, and accelerates itself as well. The only difference between the airplane and the rocket is that the rocket carries the stuff it accelerates (and ejects) while the airplane can use the air that is already present all around it. Note that while this is the basic explanation, the situation with the rocket is made somewhat more complicated by the fact that as the rocket loses fuel it also loses momentum because momentum is velocity times mass and the lost fuel lowers the mass of the rocket. You might want to look up Tsiolkovsky's rocket equation if you want more information.
Why cant you launch a rocket during the winter?
You can launch a rocket in the winter.
How do you spell launch a rocket?
That is the correct spelling of the verb "launch" as in launching a rocket.

What was the name of the rocket used to launch Apollo 13?
The rocket to launch Apollo 13 was the Saturn 5 rocket.
Was George Stephenson's rocket launch in 1821 successful?
George Stephenson did not do a rocket launch in 1821. Rocket was the name of his locomotive.
How does launching your rocket relate to this law of motion?
If a rocket is at rest (zero momentum) in outer space, where there is no gravity, then as long as there are no Outside forces on it its momentum must always be zero (consevation of momentum). This must be true even if an internal explosion brakes it into pieces. The pieces must fly off in such a way that their net vector momentum is zero. Turning on the engine is like an internal explosion. The hot gasses, which have mass, are ejected out the back at high velocity so the gas has momentum. In order to keep the total momentum zero the rocket must move forward so its momentum just equals the backward momentum of the gasses and the net momentum of both is zero. The same is almost true when taking off from earth. Because of the Earth's gravity(outside force) the upward momentum of the rocket won't quite equal the downward momentum of the gasses but its almost the same.
