Answer:
The kinetic energy is
Explanation:
From the question we are told that
The radius of the orbit is
The gravitational force is
The kinetic energy of the satellite is mathematically represented as
where v is the speed of the satellite which is mathematically represented as
=>
substituting this into the equation
Now the gravitational force of the planet is mathematically represented as
Where M is the mass of the planet and m is the mass of the satellite
Now looking at the formula for KE we see that we can represent it as
=>
substituting values
