Quizplus · Accepted Answer

The answer is B because the horizontal motion of Bullet B does not affect its vertical motion (free-fall). Both bullets will fall under the force of gravity alone, and since they were both released from the same height at the same time, they will hit the ground at the same time. The horizontal velocity of Bullet B will not affect its time of flight or its vertical velocity.
