Since we know that Mount Everest is 8848 meter high, we just have to add that to the radius of the Earth and find the radius of the centripetal force. We have that the radius is 6408848 meters.
Now, we need the formulas:
F=(mv^2)/r and
F=(GMm)/r^2
We combine the tow formulas and get
(mv^2)/r=(GMm)/r^2
Solve for v and get
v=sqrt(MG/r),
G being 6.67 x 10^-11
M being the mass of the Earth, or 6.4 x 10^24
and r we already solved
So, plug in, and the answer we get is 7902.2 m/s

The horizontal velocity required for a satellite to be placed in a circular orbit around Earth from the top of Mt Everest, which is approximately 8,848 meters above sea level, would be about 7,900 meters per second. This velocity is necessary to counteract the Earth's gravitational pull and maintain a stable circular orbit at that altitude.

Why do Satellites travel in a circular path?
Satellites orbit the Earth or other bodies due to a careful balance of their velocity and the gravitational attraction of the body. Essentially gravity pulls them down but their velocity moves then out (Newton's Fist Law of Motion) at the same rate. They keep missing the body they orbit.The path is not necessarily circular since the gravity over the Earth varies with the density of the ground below the satellite. They are also satisfied to be in an elliptical orbit (closer at some times than others). The moon is a good example of a satellite in an almost circular elliptical orbit. comets have wildly elliptical orbits.
A golf is hit and leaves the tee with a velocity of 25.0ms at 35.0 degrees with respect to the horizontal What is the horizontal displacement of the ball?
To find the horizontal displacement of the ball, you can use the equation of motion in the horizontal direction, which is given by: horizontal displacement = initial velocity * time * cos(angle). Given the initial velocity is 25.0 m/s and the angle is 35 degrees, the horizontal displacement can be calculated once the time of flight is known.
The force of gravity is responsible for continuously changing the what of a satellite?
The force of gravity is responsible for continuously changing the velocity or speed of a satellite as it orbits around a larger body, such as a planet or a star. This change in velocity helps to maintain the satellite's orbit and keep it in motion around the larger body.
Which physical quantity is conserved of an earth satellite?
The total mechanical energy of an Earth satellite (kinetic energy + potential energy) is conserved in the absence of non-conservative forces like air resistance or atmospheric drag. This means that as the satellite orbits Earth, its total energy remains constant.
Does a horizontal line on a velocity vs time graph mean an object has stopped?
Not necessarily. If the horizontal line is laying on top of the x-axis, then the speed is zero at any time, and the object isn't moving. But if the horizontal line is parallel to the x-axis, then the object is moving with constant speed.
The velocity required to keed a satellite in orbit around the Earth is called?
circular velocity
Do horizontally launched projectiles have a horizontal acceleration?
No, horizontally launched projectiles do not have a horizontal acceleration after being launched because there are no horizontal forces acting on them once they are in motion. Horizontal acceleration only occurs if there is a change in velocity in the horizontal direction, which would require a horizontal force.
What is the horizontal component of the initial velocity of the ball?
The horizontal component of the initial velocity of the ball is the velocity in the horizontal direction at the moment the ball is launched. It represents the speed and direction at which the ball is moving side-to-side.
Is it true that a projectile launched into space at any angle will have a constant horizontal velocity?
Yes, in the absence of air resistance, a projectile launched into space at any angle will have a constant horizontal velocity. This is because there are no horizontal forces acting on the projectile once it is launched.
What is the formula for a horizontal launched projectile?
The formula for the horizontal distance traveled by a horizontally launched projectile is: range = initial velocity * time. This formula assumes that there is no air resistance and that the projectile is launched horizontally.
What is the shape of the orbit when the velocity of the satellite is everywhere perpendicular to the force of gravity?
The orbit is a circle. When the velocity of the satellite is perpendicular to the force of gravity, it means the gravitational force only provides the centripetal force needed for circular motion.
If a satellite's radial velocity is zero at all times its orbit must be elliptical or parabolic?
Not necessarily. A circular orbit around a central body, such as a planet, would also have a radial velocity of zero at all times. In a circular orbit, the satellite's velocity vector is always perpendicular to the radius vector, resulting in a constant radial velocity of zero.
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 the initial direction on the projectile's velocity?
The initial direction of a projectile's velocity is typically determined by the angle at which it is launched relative to the horizontal plane. This angle will influence both the horizontal and vertical components of the velocity.
What is the relationship between the horizontal and vertical components of velocity for a projectile launched at an angle between 0 and deg and 90 and deg?
The horizontal and vertical components of velocity for a projectile launched at an angle between 0 and 90 degrees are independent of each other. The horizontal velocity remains constant throughout the motion, while the vertical velocity changes due to the effect of gravity. The initial velocity of the projectile is divided into these two components based on the launch angle.
What is the horizontal distance traveled by a projectile?
The horizontal distance traveled by a projectile is determined by the initial velocity of the projectile, the angle at which it was launched, and the time of flight. It can be calculated using the equation: horizontal distance = (initial velocity * time * cosine of launch angle).
Is the satellite accelerating?
Yes, the satellite is accelerating because it is revolving around our earth and in a circular motion so its velocity changes every second so it is accelerating.A2. No, the satellite is not accelerating. Acceleration is defined as the rate of change of velocity. But, its velocity is constant. The centrifugal effect is exactly balanced by the pull of gravity (assuming a circular orbit).But a nice question. The net acceleration between these forces is zero.
