To determine when a rock hits the water, you would typically need to consider the following factors: the height from which the rock is dropped, the acceleration due to gravity, and the time it takes for the rock to fall.
Assuming you are conducting an experiment or simulation, here’s how you can set up a table with a reasonable scale for the range of potential heights:
Table Setup for Rock Fall Experiment
-
Height (meters): This is the height from which the rock is dropped. It can be set up incrementally from 1 meter to, say, 100 meters, depending on practical limits and the context of your experiment.
-
Time (seconds): This column will contain the calculated or measured time it takes for the rock to hit the water once dropped from each corresponding height.
Example Table:
| Height (m) | Time (s) | |------------|------------| | 1 | 0.45 | | 2 | 0.63 | | 3 | 0.78 | | 4 | 0.90 | | 5 | 1.01 | | 10 | 1.43 | | 20 | 2.00 | | 30 | 2.45 | | 50 | 3.19 | | 75 | 4.00 | | 100 | 4.52 |
Notes:
- You can use the formula for free fall: \( t = \sqrt{\frac{2h}{g}} \), where \( t \) is the time in seconds, \( h \) is the height in meters, and \( g \) is the acceleration due to gravity (approximately \( 9.81 , m/s^2 \)).
- For more precision in real-world conditions, factors like air resistance and the shape of the rock may require additional consideration.
- The scale can also be adjusted based on the purpose of the study; for example, if you only need to explore lower heights, you could limit the range from 1 to 20 meters.
This setup allows you to analyze the relationship between height and time, facilitating the determination of when the rock hits the water.
