While exploring the canopy of the rainforest in equatorial South America, Anastasia falls from a branch 32.0 meters high. Exactly 1.2 seconds later Joe falls from the same branch. How high above the ground is Joe when Anastasia splats into the mud below?
h = Hi + Vi t + (1/2) a t^2 ,,, here Vi = 0
how long to hit the ground from 32 meters?
0 = 32 - 4.9 t^2
t = 2.56 sec to hit ground
-----------------
2.56 - 1.20 = 1.36 sec joe in air
h = 32 - 4.9 (1.36)^2
= 32 - 9.06
= 22.9 meters
