An orange is dropped at the same time and from the same height that a bullet is shot horizontally from a gun. Which of the following is true?

This is a classic example of how gravity acts independently of horizontal motion. Both the orange and the bullet are subject to the same gravitational force, which causes them to accelerate downward at the same rate, regardless of their horizontal velocities.

The orange and the bullet will fall at the same rate, meaning they will hit the ground at the same time.

So$,$ the correct answer is D$.$ The two objects will hit the ground at the same time.
