When an object strikes the ground, what does the equation s(t) equal?

The correct answer is that s(t) equals 0 when an object strikes the ground. In the context of this question, s(t) represents the vertical position of the object at time t, typically measured from a reference point like the ground level.

When an object is in free fall and hits the ground, its vertical position is at the ground level, which is commonly defined as zero in many mathematical models. Thus, s(t) = 0 indicates that the object has reached ground level after its descent.

This understanding aligns with the physics of free fall, where the object's height above the ground decreases until it reaches the point of impact. Therefore, at the moment the object strikes the ground, its height, represented by s(t), is zero.
