Given data:
Mass;
[tex]m=18.6\text{ kg}[/tex]Velocity;
[tex]v=31.1\text{ m/s}[/tex]The kinetic energy is given as,
[tex]K\mathrm{}E\mathrm{}=\frac{1}{2}mv^2[/tex]Substituting all known values,
[tex]\begin{gathered} K\mathrm{}E\mathrm{}=\frac{1}{2}\times(18.6\text{ kg})\times(31.1\text{ m/s})^2 \\ =8995.053\text{ J} \end{gathered}[/tex]Therefore, the kinetic energy is 8995.053 J.
