Answer:
first stone
Step-by-step explanation:
The first stone is traveling faster when it hits the ground.
When both stones are released at the same time, the horizontally thrown stone (the first stone) will have an initial horizontal velocity while its vertical velocity is zero. On the other hand, the vertically dropped stone (the second stone) will have zero initial horizontal velocity but will have an initial vertical velocity due to gravity.
Since the horizontally thrown stone has an initial horizontal velocity while the vertically dropped stone does not, the horizontally thrown stone will travel a horizontal distance before hitting the ground, while the vertically dropped stone will fall vertically straight down. Therefore, the horizontally thrown stone will reach the ground faster, as it covers both horizontal and vertical distances, while the vertically dropped stone only covers the vertical distance.
So, the correct answer is: The first stone.
