When a boat is dropped off a cliff and falls for 4.54 seconds before hitting the water below. how for did the boat fall in those 4.54 seconds?

The question is how far not how for

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

answer(20) psi;
