At a particular point in orbit a satellite in an elliptical orbit h as a gravitational potential energy of 5000MJ with respect to Earth’s surface and a kinetic energy of 4500MJ. Later in its orbit, the satellite’s potential energy is 6000MJ. What is its kinetic energy at that point?

Respuesta :

Answer:

kinetic energy at that point is 3500 MJ

Explanation:

Given data

potential energy = 5000 MJ

kinetic energy = 4500 MJ

satellite’s potential energy is 6000 MJ

to find out

kinetic energy

solution

we know that total energy is sum of kinetic energy and  potential energy

so kinetic energy will be

kinetic energy = total energy - potential energy     ................1

here

total energy  = 5000 +  4500 = 9500 MJ

so  now put all value in equation 1

kinetic energy = total energy - potential energy  

kinetic energy = 9500 - 6000 = 3500

so  kinetic energy at that point is 3500 MJ
