a coin us drooped into a deep well and is heard to hit the water 3.41s...
Problem: A coin is dropped into a deep well and is heard to hit the water 3.41s after being dropped. Determine the depth of the well.
Solution:
To determine the depth of the well, we need to use the equation of motion for a freely falling object. The equation is:
h = 1/2 gt^2
where h is the height or depth of the well, g is the acceleration due to gravity (9.8 m/s^2), and t is the time it takes for the coin to hit the water.
Step 1: Identify the given values
t = 3.41s (the time it takes for the coin to hit the water)
g = 9.8 m/s^2 (acceleration due to gravity)
Step 2: Substitute the values into the equation
h = 1/2 gt^2
h = 1/2 * 9.8 m/s^2 * (3.41s)^2
h = 1/2 * 9.8 m/s^2 * 11.6281s^2
h = 56.9054m
Step 3: Round off the answer to the appropriate number of significant figures
The answer is 57m.
Conclusion: The depth of the well is 57 meters.
