What else can I help you with?
A rocket that moves upward from earth's surface at escape velocity will?
Escape the earth's gravitational pull and continue out into space. However, a rocket does not need to be launched at the escape velocity as it can continue to accelerate as it climbs. A gun projectile would need to be fired with the escape velocity. In a perfect system with only the projectile and the Earth: If the projectile is fired with the exact escape velocity it will travel to infinity away from the Earth. Upon reaching infinitely far away from Earth the projectile would have zero velocity. All of its kinetic energy (movement) would be transferred to potential energy.
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 would be the angle with which the projectile should be projected to form semi circle trajectory?
If you were on the earth you would not be able to perform this feat. The only non-practical method of doing this is to be in space and shoot horizontally. Your trajectory is always a parabola unless you reach escape velocity.
How are the mass of the body and escape speed related?
The greater the mass of the planet, the greater will be the escape velocity.
The more massive is an object and the smaller is its radius the greater or smaller is the escape velocity from it?
For two bodies with equal radius, the more massive has the greater escape velocity. For two bodies with equal mass, the one with smaller radius has the greater escape velocity. Both conditions listed in the question indicate greaterescape velocity.
How do sattalites get up in to space?
escape velocity of satellite is greater
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
What happen to a rocket which rises from the earth but never attains escape velocity?
"Escape velocity" is a myth, a poorly understood fiction. "Escape velocity" is the initial velocity needed for a projectile WHEN FIRED if you want the projectile to leave the Earth entirely. Rockets, which can accelerate for a long period, never need to come anywhere close to the Earth's escape velocity of 7 miles per second in order to leave the Earth behind. However, in order to attain a stable orbit, satellites do need to accelerate to fairly high velocities; about 18,000 miles per hour in low orbit, somewhat more slowly in higher orbits.
What is the escape velocity of the Sun in miles per hour?
The escape velocity of our sun is nearly 1.4 million mph(1,381,755.55 mph), about 55 times greater than Earth's.
Can light escape black holes?
No. The escape velocity of a black hole is greater than the speed of light.
Is escape velocity bigger than orbital velocity?
Yes, escape velocity is greater than orbital velocity. Escape velocity is the minimum speed required for an object to break free from the gravitational pull of a celestial body and move into space. Orbital velocity is the speed required for an object to maintain a stable orbit around a celestial body.
Is escape velocity of light infinity?
Not at all. It would take an infinitely large mass to produce an infinite escape velocity, and no such infinite mass exists. Furthermore, the escape velocity for any object is the same no matter what is trying to escape, so light does not have its own escape velocity. This question presumably concerns black holes. Light does not escape from black holes because the escape velocity is greater than the speed of light. The speed of light is not infinite, it is 300,000 kilometers per second.
