​A hunter aims his gun at a point between the eyebrows of a monkey sitting on a branch of a tree. Just as he fires, the monkey jumps down. The bullet will:

a​hit the monkey at the point aimed ​
bhit the monkey below the point aimed
chit the monkey above the point aimed
dmiss the monkey altogether
✓ Correct answer: a) ​hit the monkey at the point aimed ​
ExplanationBoth the bullet and the monkey experience the same downward acceleration due to gravity provided the air resistance is negligible.When the hunter fires the bullet, the bullet starts moving along a curved trajectory due to the combined effects of its horizontal velocity and the vertical acceleration caused by gravity.When the monkey jumps, it also begins to fall freely under gravity with an initial vertical velocity of zero.Science and Technology 587 Since the hunter aims directly at the monkey at the moment of firing, the bullet and the monkey will both fall the same vertical distance due to gravity at the same time.Therefore, the bullet will hit the monkey at the point aimed.233
