GENERAL KNOWLEDGE

Detailed explanation-1: -When the projectile reaches a vertical velocity of zero, this is the maximum height of the projectile and then gravity will take over and accelerate the object downward. The horizontal displacement of the projectile is called the range of the projectile, and depends on the initial velocity of the object.

Detailed explanation-2: -As the projectile moves upwards it goes against gravity, and therefore the velocity begins to decelerate. Eventually the vertical velocity will reach zero, and the projectile is accelerated downward under gravity immediately. Once the projectile reaches its maximum height, it begins to accelerate downward.

Detailed explanation-3: -At maximum height, velocity of the body is zero and acceleration is the acceleration due to gravity which is constant.

Detailed explanation-4: -In projectile motion, the projected material or body moves in the air and experiences only an acceleration (g) vertically downwards at each instant. Therefore, the acceleration experienced by the projectile at the maximum height will be 9.80 m/s2 9.80 m / s 2 in the vertically downward direction.

Detailed explanation-5: -A vertical velocity of zero represents the apex of the trajectory, meaning that the projectile has reached its max height. During the downward flight of the projectile, vertical velocity increases due to the effect of gravity.
