SUMMARY
The discussion centers on calculating the airtime and impact velocity of a water balloon thrown downward at an initial velocity of 15 m/s from a height of 25 meters. The correct equation to use is y = y(i) + v(i)t + 1/2gt², where g is the acceleration due to gravity, approximately 9.8 m/s². The airtime ends when the balloon reaches the ground, which occurs when y equals 0. Participants emphasize the importance of understanding the physics concepts before applying equations.
