Detailed explanation-1: -The highest point in any trajectory, called the apex, is reached when v y = 0 .
Detailed explanation-2: -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-3: -Yes, due to-ve acceleration along vertical direction velocity keep on decreasing and at the highest it becomes zero.
Detailed explanation-4: -Hence if the projecting point and the landing point are on the same plane, then the projectile will have the greatest velocity equal to the initial velocity of the projectile, when it hits the ground.
