Tom has built a large slingshot. He thinks he can model the slingshot like an ideal spring with a spring constant of 45.0 N/m. When he pulls the slingshot back 0.235 m from a non-stretched position, it just does not launch its payload as far as he wants. His physics professor "helps" by telling him to aim for an elastic potential energy of 22.0 J. How much elastic potential energy is the slingshot storing BEFORE Tom changes his design? A. 1J B. 22J C. 4J D. 11J
