what is the speeed of a rocket?

The speed depends on what you want to accomplish.  If a rocket pushes a craft slower than 5 miles per second (mps), the craft will fall back to Earth.  If the rocket gets the craft to 5 mps, the craft can orbit Earth in more or less a circle.  If a rocket gets a craft to 7 mps or more, the craft will leave Earth all together.

Okay, here you are.\n\nAlex's rocket:\n\nDistance: 900 feet \nRate: 112.5 f/s\nTime: 8 seconds\n\nKeesha's rocket:\n\nDistance: 900 feet\nTime: 5 seconds\nRate: 180 f/s

Aerial.  Its from space.

it is a russian built medium range multiple rocket launcher. its the worlds best for range and destructive powerness, here ill give you the link

if a rocket were to "stop"  in space  it would come tumblin down like a rock. a rockets orbit is what keeps it up there.  if you meant how does it dock or move its by using stabilizer rockets

use a pop bottle quarter fill wth water, and seal with a rubber cork(one with a hole in the middle this is where you put your compressor attachment)  add fins to your bottle just like a real rocket\n\nuse a half pipe as a ramp and angle it a 45 degrees ataach the compressor to the bottle and turn on.  when the air pressure gets high enough the cork will shoot out and the rocket will fly.  try different amounts of water and change the angle

Ramjets suck in air in a scoop and an engine accelerates the air coming in and blows it out with much greater force.  Rocket engines don't suck in air, they use "combustion" and burn fuel to generate thrust.  An airplane engine is a form of a ram jet.  It sucks air in the front and blows it out the back.

Just watch a NASA space rocket take off. \n\nThe enegergy created to get a rocket off the ground and into space comes from the power generated by the controlled mixing (fusion reaction) of liquid Hydrogen and Oxygen.

These are just a few web sites that will show you different ideas.  Basically, they all involve mizing baking soda with an acid, whether it's leamon juice or vinager.  How exactly you want the rocket to look and what you want to shoot in the air is up to you.  Look at these sites to give you some ideas.  Have fun, and be safe!

It was a Delta IV rocket launching a military weather satellite.\n\nI was hoping to go take some pictures but could not fit it into my schedule.

Mass transfer.\n\nThe mechanism is one by Newton, not Einstein, and it is Newton's 3rd law.\n\nThis mechanism is the whole action-reaction thing and applied to the rocket is simply; as the fuel is burned and exhaust expelled the expulsion of the exhaust mass is what propels the rocket in the opposite direction.

an unmanned self-propelled guided vehicle that sustains flight through aerodynamic lift for most of its flight path and whose primary mission is to place an ordnance or special payload on a target.\ncruise missle is a missle that is targeted using a computer built on to it that guides its rockets to hit the target. it manually corrects itself wit computers to hit the target.\n\na ballistic missle is one that only uses the laws of ballistics (angle of launch and the fuel burned) to hit its target. Once it is fired its movement cannot be altered.

A rocket is subjected to four forces in flight; weight, thrust, and the aerodynamic forces, lift and drag.\n\nat rest I will denote the launch pressure by the symbol ps. The pressure exerts an equal force on all sides of the pressure vessel, the cone of the engine. Because the rocket is free to move along the launch mechisims, the pressure exerts a vertical force given by: \n\nFp = (ps - po) * A \n\nwhere Fp is the pressure force, po is the atmospheric pressure, and A is the cross-sectional area of the rocket tube. The net force acting on the rocket is the difference of the vertical pressure force and the weight W of the rocket: \n\nFnet = (ps - po) * A - W \n\nTo simplify the analysis, we are going to assume that the length of the launch tube is small relative to the length of the rocket. As the rocket moves, the pressure remains fairly constant inside the tube. In reality, there is a slight decrease in pressure as the volume increase, but we are going to neglect that effect to simplify this analysis. With a constant pressure, and constant pressure force, we can use a simple algebraic form of Newton's second law to determine the acceleration a, velocity v and the distance y which the rocket moves along the launch tube: \n\nFnet = m * a \n\nm * a = (ps - po) * A - W \n\nwhere m is the mass of the rocket This equation can also be written as: \n\nW * a = g * ((ps - po) * A - W) \n\nwhere g is the gravitational acceleration, which is equal to 32.2 ft/sec^2 or 9.8 m/sec^2 on the surface of the Earth. The value of g is different on the Moon, and on Mars. The weight W is equal to the mass times the gravitational acceleration. Now divide both sides by the weight to determine the rocket acceleration along the launch tube: \n\na = g * ((ps - po) * A / W - 1) \n\nFor a constant acceleration, the velocity v and distance traveled y are given by: \n\nv = a * t \n\ny = .5 * a * t^2 \n\nwhere t is the time. Using the length of the launch tube L, we can now solve for the lift off time - TLO by using the second equation: \n\nTLO = sqrt (2 * L / a) \n\nand then using this time, we can use the first equation to solve for the velocity at the end of the tube: \n\nv = TLO * a \n\nv = sqrt ( 2 * L * a) \n\nAs the rocket clears the end of the launch tube (t = TLO+), the air inside the rocket, at pressure ps, will rush out the exit and the pressure will equalize with free stream inside the tube. In reality, this will provide an additional amount of thrust T given by: \n\nT = m dot * Ve \n\nwhere m dot is the air mass flow rate out of the tube, Ve is the exit velocity of the air. For an air rocket, with no nozzle and small volume, this additional thrust is small relative to the weight of the rocket, and we will ignore this effect. \n\nThe velocity v at the end of the launch tube is used as the initial velocity in the flight equations to determine the flight trajectory of a rocket.

I'm pretty sure a rocket-propelled grenade is not a shape charge(it's just a grenade mounted on a rocket-hence the name). I don't know what the temperature is, but it's gotta be high enough to melt most heavy metals.

Properly named "launch vehicles", these are a class of rockets which are used to launch satellites into earth, moon, sun, or planetary orbits, or, to lauch interplanetary payloads to objects in our solar system.\n\nA launch vehicle can be manned or un-manned. Unmanned vehicles are usually referred to as "Expendable Launch Vehicles (ELVs)", since most of the vehicle is not recovered for re-use. \n\nExamples:\nELVs: Atlas-Centaur, Titan-Centaur\nManned: Shuttle, Saturn V\n\nMore on rockets from Wikipedia:\nhttp://en.wikipedia.org/wiki/Rocket\n\nHope this helps!
