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.

dropped it from your hand.

What velocity of a projectile is considered to be constant?
horizontal
Which of the velocity component of projectile changes and other remain constant why?
the horizontal component remain unchanged because there in no acceleration in horizontal direction
What is the value of constant horizontal velocity?
In projectile motion, since , there's no force in the horizontal direction which can change the horizontal motion therefore the horizotal velocity remains conserved Vx=Vox= Vocos theta by using above formula , constant horizontal initial or final velocity can be found. since Initial = final horizontal velocity.
How fast is a projectile moving at the top of its trajectory?
The vertical velocity is 0. The horizontal velocity is constant during the entire trajectory (and may be zero).
Is it true that a projectile launched into space at any angle will have a constant horizontal velocity?
If space were entirely empty this would be true, but even minute gravitational forces can change the trajectory and velocity of a projectile.

If you keep the velocity of projection constant and change the angle of projection from 75 to 45 what will happen to the horizontal distance the projectile travels?
The horizontal distance will be doubled.
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.
What is the name of the curved path of a projectile that accelerates only in the vertical direction while moving at a constant horizontal velocity?
rainbow trajectory
What is the combination of horizontal motion with constant velocity and vertical motion with constant acceleration?
That combination is called "projectile motion". In the absence of air resistance, its shape is always a parabola.
In the absence of air friction does the horizontal component of a projectile's velocity change as the projectile moves is this True False?
A projectile will travel on a straight line unless external forces act upon it. Gravity will pull the projectile downward, i.e. affect its vertical velocity component. This is why the projectile will decelerate upwards, reach a maximum elevation, and accelerate back down to earth. The force vector of air resistance points in the opposite direction of motion, slowing the projectile down. For example, If the projectile is going forward and up, air resistance is pushing it backwards (horizontal component) and down (vertical component). Without air resistance, there is no external force acting upon the horizontal velocity component and the projectiles ground speed will stay constant as it gains altitude and falls back down to earth.
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?
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.
