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?

Answer provided by our tutors

let time taken to land = x sec.

distance covered = 16feet = 4.88m

acceleration = 9.8m/s^2

initial velocity = 0

4.88 = 1/2 / 9.8 * x^2

=> x = .998sec
