Question
The velocity of a projectile, fired horizontally from a height, just before it strikes the ground
Correct Answer
Option C is the correct answer.
Detailed Explanation
Throughout its flight, the horizontal velocity remains constant at its initial value. Meanwhile, gravity causes a vertical velocity to build up over time. Just before impact, the projectile has a non-zero horizontal component and a non-zero vertical component, resulting in a velocity vector at an angle below the horizontal.
Hint
Does the horizontal motion ever stop? Does the vertical motion start from zero and increase?
