A satellite with a mass of 110 kg and a kinetic energy of 3.0 ´ 109 J must be moving at a speed of
djverab [1.8K]

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,

                                   KE=\frac{1}{2}mv^2

  • Given that,

                                   m=110kg\\KE=3.08*10^9J\\

  • We have to find the speed of the satellite,

                               v=\sqrt{\frac{2KE}{m} } =\sqrt{\frac{2*3.08*10^9}{110} } =7.483*10^3 m/s

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