SUMMARY
The displacement of a wrench dropped from a height can be calculated using the kinematic equations of motion. Given that the acceleration due to gravity (g) is 9.8 m/s², after 7 seconds, the displacement can be determined using the formula: displacement = (1/2) * g * t². Substituting the values, the displacement after 7 seconds is 240.1 meters downward. Understanding the role of g as a constant acceleration during free fall is crucial for solving such problems.
