The kinetic energy $K$ of an object is given by the formula $K = \frac{1}{2} m v^{2}$ , where $m$ is the mass in kilograms and $v$ is the speed in meters per second. An object has a kinetic energy of 25 joules and is moving at a speed of 5 meters per second. What is the mass, in kilograms, of the object?
