According to the statement of the problem, the following relationship of direct proportionality is built:
Where:
- Time spent by the stone, measured in seconds.
- Height change experimented by the stone, measured in meters.
- Proportionality constant, measured in
.
First, the proportionality constant is determined by clearing the respective variable and replacing all known variables:
If and
, then:
Then, the expression is . Finally, if
, then the time is:
The stone would take approximately 10.107 seconds to fall 500 meters.
