## Step 1<br />The problem provides the formula for kinetic energy, which is \( K = \frac{1}{2}mv^2 \). We are asked to express the mass, \( m \), in terms of the velocity, \( v \), and the kinetic energy, \( K \).<br /><br />## Step 2<br />To isolate \( m \), we need to multiply both sides of the equation by 2 and then divide by \( v^2 \). This gives us the equation \( m = \frac{2K}{v^2} \).<br /><br />## Step 3<br />Comparing this equation with the options given, we can see that option C matches our derived equation.
