The time taken for the phone to hit the ground is 15 seconds.
<h3>How to calculate the time?</h3>
Initial height = 3600 ft
h(t) = -16t² + initial height.
h(t) = -16t² + 3600
h(t) = 3600 - 16t²
When the phone hit the ground
h(t) = 0
3600 - 16t² = 0
16t² = 3600
t² = 3600/16
t² = 15
The time taken is 15 seconds.
