Question

Why is velocity 0, when an object reaches it maximum height ​

Answer 1

Explanation:

The maximum height of a object in a projectile trajectory occurs when the vertical component of velocity, vy , equals zero. As the projectile moves upwards it goes against gravity, and therefore the velocity begins to decelerate . Once the projectile reaches its maximum height, it begins to accelerate downward.
