The kinetic energy \( K \), in joules, of an object is given by the formula \( K=\frac{1}{2}mv^2 \) where m is the mass of the object, in kilograms, and \( v \) is the velocity of the object, in meters per second. If the kinetic energy of a certain object can be found by using the formula \( K=82v^2 \), what is the mass of the object, in kilograms?
