The kinetic energy of an object is given by the formula $K=\frac{1}{2}m{v}^2$, where $K$ is the kinetic energy in joules, $m$ is the mass in kilograms, and $v$ is the speed in meters per second. If an object has a mass of 2 kilograms and a kinetic energy of 25 joules, what is its speed in meters per second?
