A body of mass $2\ kg$ is moving with the velocity of $5\ m/s$. Find its kinetic energy.
Given:
Mass of the body $m=2\ kg.$
Velocity of the moving body $v=5\ m/s$
Therefore, kinetic energy $K=\frac{1}{2}mv^2$
$=\frac{1}{2}\times2\times5^2$
$=25\ Joule$
Therefore, kinetic energy of the moving body is $25\ Joule$.
