# Calculate your Kinetic Energy in Joules if you weigh 50 kg and you are walking 2 m/s.

## Question:

Calculate your Kinetic Energy in *Joules* if you weigh 50 *kg* and you are walking 2 *m/s*.

## Kinetic Energy :

The kinetic energy of an object is defined as the energy due to the motion of the object.

The kinetic energy of an object of mass {eq}m {/eq} and the velocity {eq}v {/eq} is given by :

{eq}K = \frac{1}{2}mv^{2} {/eq}

## Answer and Explanation:

Given that:

{eq}\\\\\begin{align*} \texttt{mass } (m) & = 50 \texttt{ kg} \\\\ \texttt{Velocity } (v) & = 2 \texttt{ m/s} \\\\\end{align*} {/eq}

Therefore, the kinetic energy {eq}K {/eq} is:

{eq}\\\\\begin{align*} K & = \frac{1}{2}mv^{2} \\\\& = \frac{1}{2}(50)(2)^{2} \\\\& = 100 \texttt{ Joules} \\\\\end{align*} {/eq}
