Pinata · Answer 1

D. be over the bomb.

Explanation:

When the bomb is dropped from the plane, it has the same horizontal speed as the plane since the plane is not accelerating.

The vertical motion of the bomb during the drop is purely under gravity and does have any effect on the horizontal velocity of the bomb; it determines how long it takes for the bomb to hit the ground.

Hence, the bomb and the plane are actually travelling with the same horizontal speed and will have travelled the same distance by the time the bomb lands.
