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 \( K=34v^2 \), what is the mass of the object, in kilograms?
