Inverse and Direct Variation Word Problems - Examples

In physics, objects in motion have kinetic energy, $KE$, that is directly proportional to mass and velocity by $KE = \frac{1}{2}mv^{2}$. If an object with a mass of $10\,kg$ has $500$ joules of kinetic energy, how much kinetic energy would a $25\,kg$ object have moving at the same velocity?
