Let's take your equation y = vy * t - .5 * t * t and let's add some
numbers.
velocity = 1000f/s
time = 1 second
y = 1000f/s * 1s - .5 * 1s^2
y = 1000f - .5s
y = 999.5 f
I just can't believe that anything will fall 999.5 feet in one second.
Plus velocity and gravity are independent of each other.
Could someone please clue us in to what we are talking about.
