In order to calculate the tangential speed of the orbiting object Hannah need the distance of the orbiting object to Earth.
<h3>What is the tangential speed of the object?</h3>The tangential speed of an object is the linear component of the speed, which is moving in a circular path.
In terms of the gravitation constant, the tangential speed can be given as,
Here, {<em>G</em>} is the gravitation constant, (<em>m</em>) is the mass and (<em>r</em>) is the radius.
Hannah has information about an object in circular orbit around Earth.
The mass of the earth is.
The value of gravitational constant is,
The radius of the earth is,
Here, only the distance of the orbiting object to Earth is need to find the tangential speed of the object.
Hence, in order to calculate the tangential speed of the orbiting object Hannah need the distance of the orbiting object to Earth.
