The hang time in physics refers to the total time a projectile (in this case, the basketball player) spends in the air. For a hang time of 1 second, the total time up and down is 1 second, meaning the player spends 0.5 seconds ascending and 0.5 seconds descending. Using the formula for the height of a projectile (h = 0.5 * g * t^2, where g is the acceleration due to gravity, approximately 9.8 m/s^2, and t is the time in seconds), we calculate the height as h = 0.5 * 9.8 * (0.5)^2 = 1.225 meters. Therefore, the closest answer is about 1.2 meters.
