SUMMARY
The discussion centers on the relationship between final and initial y velocity in projectile motion and its impact on time until impact. It is established that while an object's final y velocity can indeed be lower than its initial y velocity due to downward acceleration, this does not directly correlate with an increase in time until the object hits the ground. Instead, the kinematics equations, which account for acceleration, should be utilized rather than the simplistic equation x/v = t. The key takeaway is that instantaneous speed in projectile motion is always affected by gravitational acceleration, leading to a decrease in velocity over time.
