You are standing on the school balcony 5 m above the floor it was a stone up into the air at speed of 18 m per 2nd the stone free falls and eventually land on the 1st floor below you. A. How far above the ground will the stone be at the top of its path? B. What was the velocity of the stone as it reaches the ground? C. How much time did it take the stone to free fall fr ok m the moment you let go until it hit the ground?

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
