GENERAL KNOWLEDGE

Detailed explanation-1: -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-2: -The horizontal velocity component (vx) describes the influence of the velocity in displacing the projectile horizontally. The vertical velocity component (vy) describes the influence of the velocity in displacing the projectile vertically.

Detailed explanation-3: -Generally, horizontal velocity is horizontal displacement divided by time, such as miles per hour or meters per second.

Detailed explanation-4: -The vertical component of velocity of a projectile at maximum height is zero because at maximum height it has only horizontal component of velocity. Was this answer helpful?
