A phone dropped at a height of 3600 ft. How many seconds will it take for the phone to hit the ground

the time of fall of the stone is 15 s.

Step-by-step explanation:

Given;

height through which the stone was dropped, h = 3,600 ft

the initial velocity of the stone, u = 0

The time of fall of the stone is calculated using the following kinematic equation;

h = ut + ¹/₂gt²

h = 0 + ¹/₂gt²

h = ¹/₂gt²

where;

g is acceleration due to gravity = 32.17 ft/s²

Therefore, the time of fall of the stone is 15 s.
