78.46 meters (257.4 feet)
It is a projectile falling with an acceleration equal to that of free fall. (an object falling in a vacuum at the earth's surface)
Gravity is forcing an object to fall to the ground. Another force is friction from air pressure on the falling object.
If an object is in "free fall", it means that the only force acting on it is gravity.
The gravity acting on a rising object and that on a falling object are the same when these objects are at the same height. What is different is that a rising object is decelerating by the force of gravity and the falling object is accelerating.

122.5 meters (402.5 feet)
when the acceleration of the freely falling object is equal to the acceleration due to gravity then there occurs free fall.
Let's imagine there is no air resistance and that gravity is the only thing affecting a falling object. Such an object would then be in free fall. Freely falling objects are affected only by gravity
At the end of 3 seconds, a falling object is falling at 65.8 mph faster than when it was released, ignoring air resistance.
The gravity acting on a rising object and that on a falling object are the same when these objects are at the same height. What is different is that a rising object is decelerating by the force of gravity and the falling object is accelerating.
A falling object.
x = 1/2 g t2 = (4.9) (10)2 = 490 meters

Such an object is said to be in "free fall".
