A pendulum is attached to a fixed point and then released with a swinging motion. Three positions ( 1,2 ; and 3 ) are marked on the path of the pendulum as it swings, as shown in the image. If the energy of the pendulum follows the Law of Conservation of Energy, which table could represent the kineric and potential energy values at the three positions? \begin{tabular}{|c|c|c|} \hline Position & \begin{tabular}{c} Kinetic Eneryy \\ \( ( \) J \( ) \) \end{tabular} & \begin{tabular}{c} Potential Energy \\ \( (\boldsymbol{J} \) \end{tabular} \\ \hline 1 & 0 & 15 \\ \hline 2 & 15 & 0 \\ \hline 3 & 0 & 15 \\ \hline \end{tabular} \begin{tabular}{|c|c|c|} \hline Position & \begin{tabular}{c} Knetic Energy \\ \( (J) \) \end{tabular} & \begin{tabular}{c} Potential Energy \\ \( (J) \) \end{tabular} \\ \hline 1 & 0 & 0 \\ \hline 2 & 15 & 0 \\ \hline 3 & 15 & 15 \\ \hline \end{tabular} \begin{tabular}{|c|c|c|} \hline Position & \begin{tabular}{c} Kinctic Energy \\ (J) \end{tabular} & \begin{tabular}{c} Potential Eneruy \\ (J) \end{tabular} \\ \hline 1 & 15 & 15 \\ \hline 2 & 0 & 15 \\ \hline 3 & 0 & 0 \\ \hline \end{tabular} \begin{tabular}{|c|c|c|} \hline Position & \begin{tabular}{c} Kinetic Energy \\ \( (\boldsymbol{J} \) \end{tabular} & \begin{tabular}{c} Potential Energy \\ \( (\boldsymbol{J} \) \end{tabular} \\ \hline 1 & 0 & 0 \\ \hline 2 & 0 & 15 \\ \hline 3 & 15 & 15 \\ \hline \end{tabular}
