The Kinetics energy vs. time graph would have more exaggerated crests and troughs, but the period would become longer.. The Potential energy vs. time graph would become a wider parabola-like shape. The Mechanical energy vs. time would take the same change as the Potential energy vs. time graph and would become a wider parabola-like shape.. The Total Kinetic Energy vs. time graph would have exaggerated crests and troughs like the Kinetic energy vs. time graph, however there would be less oscillations than if it were a 0.5 kg mass. These changes occur because the spring has a bit more difficulty trying pulling the mass back up which results in a longer period which in turn effects the shape of these graphs.
