The question is how far not how for

Answer:

101.1 m

Explanation:

From the kinematics equations

s=ut-0.5gt^{2} but since u=o and the negative implies the distance is downwards then

s=0.5gt^{2} where s is the distance, u is initial speed, t is time, g is acceleration due to gravity

s=0.5*9.81*4.54^{2}=101.099898 / approx 101.1 m
