Amusement Park Divers: Speed and Physics Analysis
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Step into the thrilling world of amusement park divers as we explore the physics behind their jaw-dropping stunts. Diving from a platform 21.3 meters (70 feet) above a pool of water, we investigate the announcer's claim that divers enter the water at a speed of 56 miles per hour (25 meters per second). We'll also uncover the possibility of divers leaping directly upward to achieve a specific water entry speed and examine the physical feasibility of such a feat. Join us for an educational journey
