GENERAL KNOWLEDGE

Detailed explanation-1: -Furthermore, since there is no horizontal acceleration, the horizontal distance traveled by the projectile each second is a constant value-the projectile travels a horizontal distance of 20 meters each second. This is consistent with the initial horizontal velocity of 20 m/s.

Detailed explanation-2: -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: -The range of a projectile is the horizontal distance the projectile travels from the time it is launched to the time it comes back down to the same height at which it is launched. In a projectile motion, there is no horizontal acceleration at work.

Detailed explanation-4: -To obtain a horizontal motion, a projectile must be launched in a straight line, and not at any angle. The velocity of the projectile varies, but the direction in which a projectile is launched should be perpendicular to the surface of the Earth.
