Question

A stone is dropped from a tower 100 meters above the ground. The stone falls past ground level and into a well. It hits the water at the bottom of the well 5.00 seconds after being dropped from the tower. Calculate the depth of the well. Given: g = -9.81 meters/second

22.5 meters
50.7 meters
100 meters
110 meters
152.45 meters

Answer 1

The distance an object falls from rest is    (1/2) (g) (T²) .

           D  =  (1/2) (9.8 m/s²) (T²)

                =  (4.9 m/s²) (5 seconds)²

                =              122.5 meters .

Since it was dropped from 100 meters above ground,
the rest of the distance was down the well.

The well is  22.5 meters deep.

Answer 2

The answer is 22.5 meters deep.

Here is the solution:-

The distance an object falls from rest is    (1/2) (g) (T²) .

          D  =  (1/2) (9.8 m/s²) (T²)

               =  (4.9 m/s²) (5 seconds)²

               =              122.5 meters .

Since it was dropped from 100 meters above ground,

the rest of the distance was down the well.

The well is 22.5 meters deep.

What is gravity?

Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.

How does gravity change with depth?

As the depth increased the mass of the earth decreases. At the surface of the earth, this value will be maximum because the radius will be maximum. When the radius becomes less this value also decreases. Hence acceleration due to gravity decreases with an increase in depth.
