How do you find the depth of a well by dropping a stone?

However, using physics it is possible to calculate the depth of the water because once dropped, the stone will accelerate due to gravity at a rate of 9.8 meters per second squared, and you can determine the distance it traveled by using the distance formula: D = v0​t + 1/2​a*t^2.

How many feet does a stone fall per second?

Gravity will accelerate any object at a rate of 32 feet per second per second.

How do I calculate well depth?

Measure from the bottom of the weight to the ground level mark on your string. This is the depth of your well.

How do I check the depth of my well water?

You can measure the depth of water by lowering a wetted steel tape to into the well until the lower part of the tape is under water. A chalk coating on the last few feet of tape indicate the exact water level.

How do you measure the depth of a well?

How fast does a pebble drop?

When you drop the pebble from 5 m above the surface, the impact time is very close to 1 s, as predicted by assuming constant near-Earth acceleration g = −9.8 m/s2.

What happens when a stone is dropped from the well?

When a stone is dropped from top of the well, it travels in air and then hits the top of water level in the well producing sound. It is this sound which takes 4 seconds to reach the top of the well from the moment the stone is dropped. Sound travels through air at 350 m/s. Asking, what is depth of the well is a wrong question?

What does depth of the well mean?

Depth of the well means the distance between the bottom of the well and the top of the water level in the well. This question is wrongly worded. The stone is dropped from top of the well. The level of water in the well is say ‘h’ metre below the top of the well.

How long does it take a stone to reach the well?

When a stone is dropped from top of the well, it travels in air and then hits the top of water level in the well producing sound. It is this sound which takes 4 seconds to reach the top of the well from the moment the stone is dropped.

How fast does the water drop from a deep well?

Most wells are shallow so ignore the terminal velocity. The speed of sound is also fast enough to ignore in many cases. A 16 foot deep well will have a one second drop. A ~64 food deep well will have a two second drop.
