Acoin falls from rest from the balcony of a building. if it takes 2.7 s for it to hit the ground, what is the final velocity of the coin?

On Earth, gravity adds 9.8 m/s to the speed of a falling object every second.

If the coin and the balcony are both on Earth, and if the falling coin
is not influenced by air resistance, then after 2.7 seconds, its speed
has increased by

(2.7 x 9.8 m/s) = 26.46 m/s .

Its final velocity is 26.46 m/s downward. 
 

Is there a picture to go along with this

If there was no gravity then their would be no downword force on the football to have it return the the grownd, and if there was no friction (mainly air friction) then there would be no opposing force the stop the ball from moving through the air allowing the ball to travle ∞.
