Detailed explanation-1: -The velocity of the horizontal component of the projectile motion is constant because there is no external force which acts on the horizontal component of the velocity, but the external force acts on the vertical component of the velocity.
Detailed explanation-2: -The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.
Detailed explanation-3: -The horizontal velocity remains constant, because there is no acceleration in that direction. The length of the horizontal velocity vector doesn’t change. THE VERTICAL & HORIZONTAL MOTIONS ARE INDEPENDENT.
Detailed explanation-4: -Hence, only acceleration and horizontal component of velocity remain constant.
Detailed explanation-5: -In the motion of projectile the horizontal component of velocity remains constant.
