A pebble is dropped into a well. It takes 15 seconds for the sound of the splash to be heard. If the speed of sound is 343 m/s how deep is the well?
Please Help!

The concept of "Pebble falling into well" is a thought experiment used to demonstrate the effects of gravity on objects. It involves dropping a pebble into a vertical well and observing its motion as it falls towards the bottom.
The speed of the pebble as it falls into the well is affected by several factors, including the height of the well, the mass of the pebble, and the strength of gravity. Other factors such as air resistance and the shape of the well may also play a role.
As the pebble falls into the well, the distance between the pebble and the bottom of the well decreases over time. This is because the pebble is accelerating due to the force of gravity and is moving closer to the bottom of the well with each passing second.
When the pebble reaches the bottom of the well, it will come to a stop. This is because the force of gravity is no longer acting on it and it has reached its maximum speed. The pebble will then remain at rest at the bottom of the well until another force acts upon it.
The mass of the pebble affects its motion as it falls into the well in two ways. First, a heavier pebble will experience a greater force of gravity and will therefore accelerate faster than a lighter pebble. Second, a heavier pebble will also have a greater inertia, making it more difficult to change its state of motion. This means that a heavier pebble may have a greater tendency to continue falling straight down into the well, without being affected by air resistance or other forces.
