Question

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

Answer 1

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.

How to solve the problem the equation of kinetic energy?

• 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.

Answer 2

In order to move at a speed of 7483 m/s, a satellite with a mass of 110 kg and a kinetic energy of 3.08× 10^-9 J must be travelling.

Understanding a body's kinetic energy is necessary in order to determine the solution.

How can the kinetic energy equation be solved?

• The phrase "kinetic energy of a body" might be used as,

                         $KE=\frac{1}{2}mV^2$

• Given that,

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

• We must determine the satellite's speed.

                        $V=\sqrt{\frac{2KE}{m} }=7.48km/s$

Thus, we can infer that the satellite will move at a speed of 7438 m/s.
