It depends on the motor. The Space Shuttle's 4-segment motor burns for 124 seconds, for instance. The Atlas V's solid rocket motors burn for 90 seconds. A common size B4 model rocket motor burns for 1 second.
it depends on the size of the rocket, the grain material, and the oxidizer to tell you how long one will burn.

What are the ingredients in rocket fuel?
There are choice of solid liquid and gas fuel propellant. For space discovery rocket it is usually use liquefied hydrogen and oxygen as fuel. Missile and ICBM use solid propellant for long storage time. Choice is depend on the type and need.
What speed does a space shuttle reach during take off?
The shuttle at takeoff is accelerating through approx. Mach 2 by the time it reaches what we call maximum dynamic pressure or Max Q. This is when the shuttle rolls back, or "throttles back", this is done by the shape of the Solid Rocket boosters. After it has reached Max Q, it then acclerates to about Mach 26 by the time it reaches MECO or Main Engine Cut Out. This is the final Orbital Velocity, they will then determine if they need a PC+1 burn, or a PC+2 burn, this is the Peri-Cythinon Burn +1 at MECO, or the Peri-Cynthinon burn +2 at the Apogee, or the highest point of the orbit, they usually have no need for a PC+1 burn, so they will do a PC+2 burn, to circularize the orbit.
What is a space shuttle's lift off speed?
Since just before liftoff the speed is zero, the speed 'at liftoff' is just a tiny bit faster than zero. The speed gets faster and faster as time passes and the rocket moves up. The Space Shuttle goes from zero to 17,000 mph in 8.5 minutes. The speed of the gases exiting the Solid Rocket Booster motor is 6,000 mph -- three times the speed of a high-powered rifle.
What determines how much thrust is generated in a solid fuel rocket engine at any given time?
The amount of exposed surface area of the fuel
How do you fly from moon to earth?
Given current technology, whilst orbiting the moon one fires a chemical propellant rocket to begin trans-terrestrial injection. This rocket adds enough speed to escape the moons gravity. If the TTI burn had the proper impulse and was executed at the proper time, the matter of returning to Earth is all about gravity.
How long does a model rocket motor last?
Provided they are kept in a dry, cool, and stable environment, they should last indefinitely. The ingredients are non-volatile, so they do not really degrade over time. If you want to know how long they burn for, you need to look at the rating on the side of the rocket. A higher thrust number means that it will burn for a shorter amount of time. Most small model rocket engines burn for 3 to 5 seconds.
What does Burn Time for a rocket mean?
The length of time from ignition of propellant to when all propellant has been consumed.
What is the function of a rocket nozzle?
The function of a rocket nozzle is to allow the thrust to be focuses and amplified. It also prolongs the burn time and greatly increases performance.
What do you mean by effective jet velocity of a rocket?
Effective jet velocity of a rocket is the increased velocity of a rocket in a short span of time. It is achieved with the use of either solid or liquid propellants.Ê
How many newtons of force does a water bottle rocket exert at the highest altitude?
At the top of the rocket's trajectory it is motionless for a brief time and the only force acting on it is that of gravity; the rocket motor has long since spent its energy.
What is the difference between soild and liquid fuel rocket engines?
A solid fuel rocket engine is just what it sounds like. The fuel inside the rocket is completely solid. In a liquid fuel rocket the fuel is a liquid. Bottle Rockets that you can buy in many stores are fueled with Solid Fuel. Most liquid fuel rockets contain 2 different types of fuel. Once that fuel is mixed and ignited you get your thrust.

When was the first liquid launched rocket?
The US's first solid fuel rocket capable launching a satellite into orbit was named Scout. I think this was the first solid fuel rocket to carry payloads into orbit because the Soviet Union did not begin it's solid rocket program until later. It is possible the Minuteman ICBM may have been the first solid rocket to reach space but in a ballistic flight (go up and fall back down like a cannon ball), but I haven't been able to find the date of the first Minuteman sub orbital flight and both rockets were developed at about the same time.
What is the length of time that a motor can safely run on starting and full load current?
It depends on the insulation provided in winding, motor can safely run on full load current. and over that it may burn but depends on cooling system of the motor. Motor can burn if insulation fails, failure of insulation depends on only the temperature rise.

What is the difference between model rockets and real rockets?
In a real rocket, there is short a time in atmosphere and the aerodynamics are less important. In a model rocket, all flight in the atmosphere and the aerodynamics are very important. In a real rocket, it has a liquid or solid rocket engine and a large propellant mass fraction. In a model rocket, it has a solid rocket engine and a small propellant mass fraction . In a real rocket, there are four forces during atmospheric flight. In a model rocket, there are four forces throughout flight. In a real rocket, there is a long powered flight . In a model rocket, it has a very short powered flight . In a real rocket, it has passive stability and active control . In a model rocket, it has passive stability and no control. In a real rocket, it has expensive materials such as aluminum, titanium, and nickel alloy. In a model rocket, it has inexpensive materials such as balsa, cardboard, and plastic. In a real model, there is a high speed and the heating is very important. In a model rocket there is low speed and the heating is not important.
Which system would be best for keeping your rocket in the air the longest?
To keep your rocket in the air for long, use larger fins at the tail end.ANS 2 - Fins don't make the slightest difference to flight time. -You need a longer burning motor.
