Problema Solution
A Bird sitting 16 feet above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? No branches interfere with its fall.
Answer provided by our tutors
let
h = 16 ft the height
g = 32.174 ft/s^2 standard acceleration of free fall
t = the time of the fall in seconds, t>0
h = (1/2)g*t^2
16 = (1/2)*32.174*t^2
(1/2)*32.174*t^2 = 16
by solving we find:
t = 0.997 s

in 0.997 seconds the apple will land of the ground.
