When an object is a projectile what happens to the x component of the velocity throughout its trajectory?

Depending on the shape, speed and change in attitude (especially a tendency to tumble) of the projectile its losses of speed at various instants along its trajectory could be quite considerable owing to friction. Under many conditions air friction is proportional to the fourth power of speed. Thus, the horizontal component of the trajectory could be subject to considerable loss of magnitude. As one would expect the shape of the projectile will affect it's path considerably too.

What is the magnitude of the velocity of a vertical projectile at its maximum height is equal to?
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
How can you throw a projectile so that it has nonzero speed at the top of trajectory?
If the projectile's velocity has a horizontal component - in other words, it doesn't go straight up - then its speed will never be zero.
In projectile motion Why is the vertical component of velocity zero at the highest point of the trajectory?
Just before it reaches the highest point, the vertical component of velocity is upward.Just after it passes the highest point, the vertical component of velocity is downward.There's no way you can change from an upward velocity to a downward velocity smoothlywithout velocity being zero at some instant. A.True.
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).
What is the vertical velocity of a projectile at the highest point in its trajectory?
The vertical velocity is zero at the highest point. It has ceased moving upward and will begin moving downward. Gravity and air resistance will have negated the original vertical velocity (y-component). So the velocity at the highest point has only a horizontal or x-component.

What is the trajectory of a projectile having velocity greater than escape velocity?
It will eventually straighten out as it escapes gravity.
What is the vertical velocity of a projectile at the lowest point in trajectory?
It depends on the angle and speed at which it is fired.
Is the acceleration of a projectile equal to zero when it reaches the top of its trajectory?
No, assuming no air resistance, there will be a constant downward acceleration of 9.8 meters per second square (assuming standard gravity). The vertical component of the velocity will be zero at the top of the trajectory.
What is the projectile theory?
if a body is thrown having initial velocity and make angle with ground this body is known as projectile and the way is calle trajectory
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.
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 at all. Horizontal component is measured as xcos(theta) Vertical component is measured as xsin(theta) Whereas theta is the angle, and x is the magnitude, or initial speed.
Projectile's vertical velocity component changes at a constant?
Gravity... I think
