What is the kinetic energy of the rocket with mass 15,000 kg and speed of 5200 m/s? A. 2.01 x 10^11 J B. 2.02x 10^11 J C. 2.03 x 10^11 J D. 2.04 x 10^11 J

Respuesta :

C. [tex]E_{k}=2.03x10^{11}J[/tex]

The kinetic energy of a body is the ability to perform work due to its movement given by the equation [tex]E_{k}=\frac{1}{2}mv^{2}[/tex].

To calculate the kinetic energy of a rocket with mass 15000kg and speed of 5200m/s:

[tex]E_{k}=\frac{1}{2}(15000kg)(5200m/s)^{2}=202800000000J=2.03x10^{11}J[/tex]
