We have the equation of motion
, where v is the final velocity, u is the initial velocity, a is the acceleration and s is the displacement.
In this case initial velocity = 2.20 m/s, final velocity = 0 m/s, displacement = 14 m
On substitution we will get 0 = 
On solving we can find the acceleration value as -0.173
So free fall acceleration = 0.173
