We know that the centripetal force on an object is mv^2/r where m is the mass of the satellite, v is the tangential velocity, and r is the distance from the center. We also know the centripetal force is the force of gravity, which is GMm/(r^2), so we have v = Sqrt(GM/r) where G is the gravitational constant and M is the mass of the Earth. The distance from the satellite to the center of the circle is 42.25*10^6 + 6.4*10^6 = 48.65*10^6 m. We then get v = Sqrt(6.67*10^(-11)*5.97*10^24*10^(-6)/4.87) = Sqrt(8.2)*10^4 m/s = Sqrt(8.2)*10 km/s
What else can I help you with?
Why There is no work done when satellite rotate around earth?
With satellites, the object is not to escape Earth's gravity, but to balance it. Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going.This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 km). Without gravity, the satellite's inertia would carry it off into space. Even with gravity, if the intended satellite goes too fast, it will eventually fly away. On the other hand, if the satellite goes too slowly, gravity will pull it back to Earth.At the correct orbital velocity, gravity exactly balances the satellite's inertia, pulling down toward Earth's center just enough to keep the path of the satellite curving like Earth's curved surface, rather than flying off in a straight line.
What will be the velocity of a satellite which is revolving around the earth in a circular orbit the radius R if the radius is increased from R to RR what will be the velocity?
the velocity will be velocity divided by square root of 2
What is geosatelite?
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east). A geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time.
Why must a horizontally moving projectile have a large speed to become an earth's satellite?
At lower speed, the object will fall back on the ground. Since, earth is curved, if the object has enought speed, the object can try to fall beyond the curvature of the earth. Thus, it will not hit ground at all. The speed to achieve it is around 8 km/s. If the object is faster than 11.4 km/s then the object will never return. It is called escape velocity.
How do satellites move in orbit?
Satellite orbit the Earth at different altitudes. A good overview of Low Earth Orbit, Medium Earth Orbit and Geostationary Orbit can be found here: http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx
The tangential velocity of an Earth satellite is its velocity?
The tangential velocity of an Earth satellite is its velocity perpendicular to the radius vector pointing towards the center of the Earth. It represents the speed at which the satellite is moving along its orbital path. This velocity is crucial for maintaining the satellite's orbit and is calculated using the satellite's distance from the center of the Earth and gravitational force acting upon it.
Which planet has the lowest orbital velocity?
Pluto is the planet that has the lowest orbital velocity relative to that of the earth. The orbital velocity of Pluto is 0.159.
What is the effect on the orbital velocity of the sattelite if its orbital radius is doubled?
You can calculate this with Kepler's Third Law. "The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit." This is valid for other orbiting objects; in this case you can replace "planet" with "satellite". Just assume, for simplicity, that the satellite orbits Earth in a circular orbit - in this case, the "semi-major axis" is equal to the distance from Earth's center. For your calculations, remember also that if the radius is doubled, the total distance the satellite travels is also doubled.
What is the value of orbital velocity?
The orbital velocity of an object depends on its distance from the center of mass it is orbiting. For example, the orbital velocity of the Moon around Earth is about 1 km/s, while the orbital velocity of the International Space Station (ISS) around Earth is about 8 km/s.
When is the earth orbital velocity the fastest?
perihelion
When is earth's orbital velocity the fastest?
perihelion
Do mercury and earth travel at the same speed?
Nope. Mercury has an orbital velocity of 47.9km/s, whereas Earth has an orbital velocity of 29.8km/s.
The velocity a rocket must reach to establish an orbit around earth is called?
The velocity a rocket must reach to establish an orbit around the Earth is called orbital velocity. It is the speed required for an object to overcome gravitational pull and maintain a stable orbit around the planet. The orbital velocity depends on the altitude of the orbit and follows Kepler's laws of planetary motion.
Launching rocket at orbital velocity from earth makes the satellite balanced. but how it is keep on revolving the earth even vacuum also have resistance why it does not stop the rotation?
it never stop rotating cus of the earth's gravity. it just the same as moon rotating around the earth. Another Answer: Orbital velocity is just that (among others). The amount of force needed to to achieve a "Free Fall" state. The satellite is actually falling back to Earth in this state and would crash back into it except for one thing. For every foot the satellite falls toward the Earth, the Earth moves a foot out of the way.
What is a geo synchronus satellite?
A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.

What will happen if a satellite has velocity which is more than orbital vellocity but less than escape velocity?
If a satellite somehow acquires too much velocity for the orbit it's in, it moves to an orbit for which that velocity is just right. That's how artificial satellites are placed into the desired orbit ... engines are fired to give them the velocity that's correct for the desired orbit, and that's where they go.
