How fast does a rocket have to go to get into space?

Answer 1

The fastest speed ever achieved by an aircraft was 7,232 km/hour (Mach 6.7) set by the experimental rocket-powered X-15. That's 0.00000002 of the speed of light.

The fastest speed of Apollo 10 on the return from the moon on May 26, 1969 was

39,897 km/h (24,791 mph). That's 0.000037 of the speed of light (more or less).

Answer 2

In theory as fast as it has fuel for. Conventional aircraft fly in the atmosphere, where they are constantly hit by small particles that causes the plane to slow down. This is not the case in space, as there are no small particles out there to slow them down. So linear momentum is conserved in space. Once you speed an object in space up to say 9000 m/s, it is going to stay at 9000 m/s unless a force is applied to slow it down.
It varies depending on the rocket and where it's going. The Saturn V rocket that took man to the moon got up to 24,500mph once it was in space and on it's way to the moon.
Not as fast as you might think. Or faster, one of the two.

A rocket launched from earth has to reach 7.9 kilometers per second in order to overcome earth's gravity and reach space. The space station generally zips along at 17,000 miles per hour.
Rockets are accelerated in accordance with Newton's laws of motion which say that if you throw mass one way you are pushed with equal force in the opposite direction.

With a rocket you must take all the mass you need for this acceleration with you in the fuel tanks because once you are up in space you can not refuel. This makes the rocket heavy and most of the fuel is used up getting into space. Once up in space (ie in orbit round the Earth) the rocket will be traveling at 6.9 to 7.8 km/s. To leave Earth orbit one needs the rocket to go even faster and the fastest rocket so far has been the New Horizons spacecraft which is a NASA robotic spacecraft currently en route to the dwarf planet Pluto. This is traveling at 16.26 km/s at the moment.
The answer to your question is determined by the type of rocket that you are referring to. There are many types that have specific purposes. There are homemade rudimentary rockets that are composed using household materials. Other more sophisticated rockets such as the famous V-2 Rockets developed by the Germans and used in the 2nd world war against British Citizens. These rockets traveled at over four times the speed of sound and reached their targets within minutes. Other man-made rockets have been specifically developed for manned space flight and need to travel fast enough to escape the Earths gravitational influence, which is about seven miles per second.

--------------------------------------------------------

about 25000 miles per hour.
17000 mph to lower Earth orbit. 25000 mph to get out of earth orbit to Lunar orbit. 25000+ to leave Earth orbit.
17,000 miles per hour

Answer 3

The X-43A can reach speeds up to mach 9.6 or 9.8 (7546 mph) i cant remember lol but the future X-43B will reach mach 2.6 or so, but will bigger and will be able to drop bombs. About the same with the X-43C. the X-43D will be almost identicle as the X-43A but will be able to reach mach 15. but to answer your question the fastest rocket is the X-43A reaching mach 9.6 (7546 mph).

Answer 4

A rocket needs to reach a speed of at least 17,500 miles per hour (28,000 kilometers per hour) to escape Earth's gravitational pull and reach space. This speed is known as escape velocity.

Answer 5

A rocket must travel at least seven miles per second in order for gravity to not be able to pull it back to Earth.

Answer 6

the anwer is not to be prised but it is 1000,00

Answer 7

Most of rockets are 8km to 10km/s. Rockets speed depend upon the escape speed of planet.

Answer 8

Its average speed in any time interval is

(distance covered)/(time to cover the distance).

Answer 9

it has to go at least 325 .
