Question

A stone is dropped off a tall building. It takes 5.3 s to hit the ground. Determine the height of the building.​

Answer 1

137.8 m tall

Step-by-step explanation:

d = do + vo t + 1/2 a t^2 d = distance (what the Q asks)

do = original position ...we will assign 0

vo = original velocity = 0 ( dropped from rest)

a = 9.81 m/s^2 ( we'll use SI units)

d = 0 + 0 + 1/2 (9.81)(5.3)^2 = 137.8 m
