SUMMARY
Harry and Hermione are analyzing the physics of jumping horizontally from a balcony 32.0 m high into a swimming pool 14.0 m away. To calculate the required horizontal velocity, they apply the equations of motion, specifically using the formula for vertical displacement, y = -0.5at², where 'a' is the acceleration due to gravity (10 m/s²). The time of flight is derived as t = √(2y/a), leading to the determination of the initial horizontal velocity needed to reach the pool.
