The steel traps the heat more making it hotter,you put this twice by the way.
Answer: A satellite with a mass of 110 kg and a kinetic energy of 3.08×10^9 J must be moving at a speed of 7483 m/s.
Explanation: To find the answer we need to know about the kinetic energy of a body.
<h3>
How to solve the problem the equation of kinetic energy?</h3>
- We have the expression for kinetic energy of a body as,


- We have to find the speed of the satellite,

Thus, we can conclude that, the velocity of the satellite will be 7438m/s.
