3. In projectile motion, what does the vertex of the trajectory's parabola represent?

A. The starting point of the projectile
B. The maximum height reached by the projectile
C. The total distance traveled by the projectile
D. The ending point of the projectile



Answer :

Final answer:

The vertex of a projectile's trajectory parabola represents the maximum height reached by the projectile.


Explanation:

The vertex of the trajectory's parabola in projectile motion represents the maximum height reached by the projectile. At this point, the object momentarily stops moving upward before descending, making it the highest point in its flight path.

To further clarify, the vertex is the peak of the parabolic path where the projectile undergoes a transition from moving upwards to moving downwards.
