The rock will take 2.80 seconds to reach the ground.
Further explanation:
Given formula
[tex]t = \frac{\sqrt{h}}{4}\\[/tex]
Here h is the height from which the object will fall and t is the time the object will take to reach the ground
Now, it is given that a rock falls from height of 125 feet
So,
[tex]t = \frac{\sqrt{125} }{4}\\t = \frac{11.18}{4}\\t = 2.795 => 2.80\ sec[/tex]
The rock will take 2.80 seconds to reach the ground.
