Two spheres are released from the same height at the same time.
Two spheres are released from the same height at the same time.
A student stands on the edge of a cliff of height \(H\) and launches Sphere 1 vertically upward with an initial speed \(v_0\). At the same instant, the student releases Sphere 2 from rest from the same height \(H\). Both spheres are in free fall until they reach the bottom of the cliff. Which of the following correctly describes the distance between the two spheres as a function of time \(t\) while they are both in the air, and provides a correct physical justification?
