Proving the feasibility of a killer whale jumping over a pier, as depicted in Free Willy, involves understanding projectile motion and the whale's physical capabilities. The whale's top speed is 13.5 m/s, and it would need to achieve a vertical jump at a 45-degree angle to clear a height of 15 feet and a length of 10 feet. However, the size and weight of killer whales make such a jump highly unlikely, as their bodies are not designed for significant aerial maneuvers like smaller marine animals. Conducting research on the force and energy required for such a jump, along with the natural behaviors of killer whales, can provide valuable insights. Ultimately, while the scene is iconic, it is important to recognize its fictional nature and the challenges of replicating it in reality.
