Earth;s Gravitational Acceleration is 9.8 m/s^(2)
Using the eq'n
a = (u - v)/t
a = 9/8 m/s^(2)
u = initial velocity of 0 m/s (lift off).
v = escape (final velicity)
t = time ( say 5 mins 300 s). (Probabky the time you can see it accelerating into space).
Hence
Algebraically rearranging
at = u - v
v = u - at.
v = 0 - (9.8 * 300 (
v = 9.8 300 = 2940 m/s
or
v = 2940 x 3600 / 1000
NB 3600 sec / hy
NNB 1000 m/ km
Hence
v = 10,500 km /hr.
This is not taking into consideration the mass of the rocket. When mass is included , although mass in reducing because of fuel combustion., a closer value is about 25,000 km/hr.
These are only hypothetical figures, but it gives an idea of the velocity required.

What is the name for the speed a rocket must reach to escape the earth's gravity?
Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.
What are to ways people can escape gravity?
People can escape gravity by achieving escape velocity, which is the speed needed to break free from Earth's gravitational pull. Alternatively, people can experience temporary weightlessness during a free fall in microgravity environments, such as in parabolic flight or in space.
How fast is the speed of gravity in mph?
According to Einstein's theory of relativity the speed of gravity is equal to the speed of light; i.e. about 671 million miles per hour. Note that this is still true in models for quantum gravity; there gravity is mediated by a massless particle and all massless particles have to travel at the speed of light.
What are two ways people can escape gravity?
Achieve escape velocity: By accelerating an object to a speed greater than the escape velocity of a planet or celestial body, it can escape the gravitational pull. Utilize propulsion systems: Using rockets or other propulsion methods to counteract the force of gravity and lift off from Earth or another planetary body.
What is Rocket speed per sec to escape from earth gravity?
the rocket speed required to escape out of the earth's gravity is known as escape velocity which is numerically equal to 11.2 km per sec.
How is the force of earths gravity overcome when an object is launched into space?
When on Earth, you can escape if you move away from the Earth at the "escape" speed. Gravity will slow you down and you will reach zero speed at an infinite distance.
What speed does the space shuttle have to reach to escape earths gravity?
17,500 miles per hour puts the shuttle in orbit. BUT the gravity is still there. I'm fact there is about 90% of the gravity while the shuttle is on the ground. That great rate of speed is required to keep the shuttle from falling back to earth. At that speed the shuttle is basically falling around the planet.
To escape from a planets gravity an object must reach a speed called the?
Escape Velocity
What is the speed of the earth to escape the sun's gravity?
The escape velocity from the Sun at the Earth's distance is about 42.1 km/s. This means that for an object to escape the Sun's gravity at this distance, it would need to travel at that speed. The Earth's orbital speed around the Sun is about 30 km/s, so it is not moving fast enough to escape the Sun's gravity.
In order to escape the gravity of earth a space vehicle near earth must have a speed of about?
about 25,000 mph to completely escape earth's gravity
Why does escape speed decrease with altitude?
I think it's because of gravity.
How using Earth's rotation speed to escape gravity?
Earth's rotation speed doesn't affect the ability to escape Earth's gravity. Escaping Earth's gravity requires reaching a velocity of about 11.2 km/s regardless of Earth's rotation speed. Earth's rotation does provide a slight boost to the velocity required to escape in the direction of the rotation.
What is the name for the speed a rocket must reach to escape the earth's gravity?
Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.
Why speed to exit atmosphere?
The earth's escape velocity, which is the speed necessary to overcome gravity and achieve either orbit or escape, is about 25,000 miles per hour (or about 7 miles per second). From a physics standpoint, it's the speed at which a rocket's kinetic energy plus its gravitational potential energy is zero. Every celestial body has a different escape velocity, depending upon its mass.
What is the max speed of a manned spacecraft?
The maximum speed reached by a manned spacecraft was during the Apollo 10 mission in 1969, when the spacecraft reached a speed of about 24,791 mph (39,897 km/h) relative to Earth. This speed was necessary to escape Earth's gravity and travel to the Moon.
How does a rocket get out of earths orbit?
A rocket gets out of Earth's orbit by achieving escape velocity, which is the speed needed to break free from the gravitational pull of Earth. The rocket's engines provide thrust to accelerate it to this speed, allowing it to overcome Earth's gravity and travel into deep space.
