Throwing Objects into the Air

This is a picture of Jenny throwing her stuffed animal into the air in her room. The vertical velocity controls the time in which this stuffed animal will spend in the air. As the object is being thrown upward its velocity decreases at a constant 10m/s  and as it falls downward its velocity increases at a constant 10m/s. However the vertical acceleration will always remain constant and the horizontal acceleration will increase and the horizontal velocity will remain constant. In this picture, the dog has just reached its stopping point before it falls to the ground. Lets say, this dog was thrown up with a velocity of 20m/s, every second its vertical velocity will decrease by 10m/s. So after two seconds, it will be 0m/s at this point in the air. And as it falls to the ground it will increase by 10m/s. Why is this? Because the force of gravity causes the velocity to decreases an object thrown up into the air 10m/s so in the middle of its path it will always have a velocity of 0m/s. The formulas you would use to determine these The formulas you would use to determine the vertical path of this stuffed animal would be v=gt and d=1/2gt(squared) and the formulas you would use to determine its horizontal  path would be v=d/t. The vertical distance measured is associated with how high where as the horizontal difference is associated with the how far factor.
