When comparing two falling objects with an initial differentiation in velocity, which aspect determines the time of impact?

The time of impact for two falling objects, especially when they have different initial velocities, is determined by their initial velocities and the height from which they are dropped. This is because the time it takes for an object to fall to the ground depends on both how fast it is moving at the start (its initial velocity) and how far it has to fall (the height).

If one object is dropped from a greater height or has a higher initial velocity, it will reach the ground sooner than an object that has a lower initial velocity or is dropped from a lower height. Therefore, both the initial velocities of the objects and their heights are crucial in calculating the time until impact.

While acceleration due to gravity influences the rate of fall for both objects, it is the combination of initial velocity and height that specifically determines the time of their impacts in this scenario.
