Free Fall Kinematic Equations which may help with this problem.

Vf=Vi + 9.8*t

 

d=Vi*t + .5*9.8*t²

 

Vf² = Vi² + 2*9.8*d

 

d= [Vi + Vf]*t/2

Answer 1

If it starts from rest and the only acceleration is the acceleration of gravity, then it falls a distance

d = gt²/2

t = time in seconds

g = acceleration of gravity = 9.8 m/s²

d = distance in meters

d = (9.8)(9)²/2 m = ? m
