A - 9.8m/s2
The terminal velocity of a falling body depends upon the drag forces encountered by the body throughout its fall. The drag forces will depend upon the shape of the body and is orientation with respect to the earth. Other factors affecting drag forces will be altitude, humidity and other variables that affect the density of the air. Here's the math. It isn't hard. Vt square root of (2mg/ρACd) where Vt terminal velocity,m mass of the falling object,g gravitational acceleration,Cd drag coefficient,ρ density of the fluid the object is falling through, andA projected area of the object. The projected area is also called the "cross-sectional area" where it's a silhouette or a "slice" across the "thickest" part of the falling object taken perpendicular to its orientation in free fall.

The answer is 91 ft, of course!
free
about 50%zedge is free but i say it 10000000% percent free
No, the word 'free' is not a noun.The word 'free' is a verb and an adjective.The abstract noun form of the verb to free is the gerund, freeing.The abstract noun forms for the adjective free are freeness and freedom.There are a few dictionaries that categorize the word 'free' as a noun, a word for 'free people'. Most dictionaries do not.When the word 'free' is used as a noun as in "land of the free...", it can be considered poetic license; an abbreviated way to say "land of the free people...".
if body is free falling state its acceleration would be 9.8meter/second2
YES
Acceleration. A free-falling object falls at constant force, and thereby at constant acceleration.
no
False
It isn't clear what experiment you are talking about.
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.
On Earth, a free-falling object has an acceleration of 9.8 meters per second2.
depends on where it falls - on mars, earth or sun... On earth, it is about 9,8 m/sec^2. In general, it can be estimated by newton's formula F=G*m*M/R^2, where G is a constant, m is mass of the falling body, M is a mass of gravitating object (earth) R is distance between them. Consequently, acceleration is F/m = ...
when the acceleration of the freely falling object is equal to the acceleration due to gravity then there occurs free fall.
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)
