In physics, kinetic energy is the energy of an object in motion. Kinetic energy, $K$, measured in joules $(\text{J})$, is calculated using the formula $K =\dfrac{1}{2}mv^2$, where $m$ is the mass of the object, measured in kilograms $(\text{kg})$, and $v$ is the velocity of the object, measured in meters per second $(\text{m}/\text{s})$.
**Rearrange the formula to solve for velocity $(v)$.**

**What is the velocity of an object with a kinetic energy of $100{,}000\text{ J}$ and a mass of $800\text{ kg}$?**
*Round your answer, if necessary, to the nearest hundredth.*
