I will try to describe in a very simple way, cuz I don't know it any other way. Take the said vector magnitude times the cosine of the angle from horizontal. In a two dimensional plane, say Joe throws a football at an angle of 10 degrees from horizontal, at 100 miles an hour. So, the horizontal component will be = 100 x cos(10)=98.48 miles an hour. The vertical component will be 100 x sin(10) = 100 x cos(80)=17.36 miles an hour. The angles are in degrees.
Yes, the horizontal velocity of a projectile is typically constant as long as there are no external forces acting on it in the horizontal direction, such as air resistance. This is due to the fact that there are no horizontal forces acting on the projectile once it is launched.
A horizontally-thrown ball begins to fall as soon as it leaves your hand. It hits
the ground some distance from you, but at the same instant as if you had just
dropped it from your hand.
sometimes unicorns fall out of my rainbow vagina, i need to go to a doctor.
Physics dictates it will fall towards earth due to its gravitational forces.

What do the horizontal motions of a projectile have in common?
The horizontal motions of a projectile are independent of its vertical motion. This means that the horizontal velocity remains constant and unaffected by gravity. Additionally, the horizontal distance traveled by a projectile is determined by the initial horizontal velocity and the time of flight.
How can the horizontal velocity of a projectile be described?
The horizontal velocity of a projectile remains constant if there is no air resistance or external forces acting horizontally. This means that the horizontal component of the projectile's velocity does not change throughout its trajectory, only its vertical component is affected by gravity.
How fast is a projectile moving at the top of its trajectory?
At the top of its trajectory, a projectile's vertical velocity is momentarily zero, while its horizontal velocity remains constant. The speed of a projectile at the top of its trajectory can be determined by calculating the magnitude of its velocity vector using the horizontal and vertical components of velocity.
Why the horizontal velocity component remains constant and the vertical velocity component continuously changes during projectile motion?
The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming no air resistance), so the velocity remains unchanged. The vertical velocity component changes due to the force of gravity, which accelerates the projectile downward, increasing its velocity as it falls.
Is it true that a projectile launched into space at any angle will have a constant horizontal velocity?
Yes, in the absence of air resistance, a projectile launched into space at any angle will have a constant horizontal velocity. This is because there are no horizontal forces acting on the projectile once it is launched.

What velocity of a projectile is considered to be constant?
The velocity of a projectile is considered to be constant when there is no change in speed and direction. This usually occurs in the absence of any external forces, such as air resistance or gravity, that could affect the projectile's motion.
How is the horizontal component of velocity for a projectile affected by the vertical component?
The horizontal component of velocity for a projectile is not affected by the vertical component. They are independent of each other. The horizontal velocity remains constant as long as there are no external forces acting on the projectile.
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
The vertical component of velocity changes due to the influence of gravity, which accelerates the projectile downwards as it moves. The horizontal component of velocity remains constant because there is no horizontal force acting on the projectile, assuming air resistance is negligible.
Which of the velocity component of projectile changes and other remain constant why?
The vertical velocity component changes due to the effect of gravity, which causes acceleration in the downward direction. The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming air resistance is negligible).
In the absence of air friction does the horizontal component of a projectile?
The horizontal component of a projectile's velocity remains constant in the absence of air friction. This means the projectile will continue to move horizontally at a constant speed unless acted upon by an external force.
A projectile is thrown with an initial velocity which has a horizontal component of 4 m s What will be its horizontal speed after 3s?
The horizontal speed of the projectile remains constant as there is no force acting in the horizontal direction to change it. Therefore, the horizontal speed of the projectile after 3 seconds will remain at 4 m/s.
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
The horizontal component of velocity remains constant because there are no horizontal forces acting on the projectile (in the absence of air resistance). The vertical component changes due to the force of gravity, which accelerates the projectile downwards.
