Answer:
The egg hits the ground after 6 seconds.
Step-by-step explanation:
Given that an egg dropped from a height of 36 feet, this means the egg was 36 feet away from the ground.
The distance is given as
d = -t² + 36
The egg hits the ground when the distance, d, from the ground is zero.
That is when
-t² + 36 = 0
Or
t² = 36
Taking square roots of both sides
t = ±√36
t = ±6
Since we are dealing with distance, we take the positive value.
So, t = 6 seconds
