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 value of the vertical speed at the highest point of the projectile's trajectory?
The value of the vertical speed at the highest point of the projectile's trajectory is the lowest speed at the maximum height reached.
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.
Is a projectile velocity the highest velocity that can be reached?
yes
Slowest point of trajectory?
The highest point is where the projectile travels slowest.
Which is the total velocity of a projectile at maximum height?
It depends. If the projectile goes straight up and straight down, its velocity will be zero at the top. If the projectile is a baseball about halfway between the pitcher and the bat, its velocity might be 150 km/h.

With out air pressure at what point or points in its path does a projectile have its minimum speed and its maximum?
Without air friction, the horizontal component of the velocity will be constant. The vertical component of the velocity will be a maximum at the lowest point in its motion and at a minimum at the highest point in its motion. Therefore the minimum is at the highest point in its motion- Potential energy max Kinetic Energy min and the maximum is at its lowest point in the motion- KE is max PE min
Why at the highest point is the change in velocity zero?
Note - the vertical velocity is zero ... there may be considerable horizontal velocity. And vertical velocity is zero because the object is going neither up nor down.
A projectile fired from the ground follows a parabolic path The speed of the projectile is minimum at the top of its path?
Yep that is correct. To understand this it may help you to draw a parabola. If you draw a line from the top of the parabola back to the ground you'd notice either side of this line is symmetrical. This isn't quite what happens to a projectile (following a parabolic path), but because of the nature of the question, effects such as air resistance can be ignored. As the projectile approaches the top of its path, the vertical component of its velocity approaches zero. As the projectile begins to fall the magnitude of the vertical component of the projectile begins to increase. The only force that acts on the projectile during flight is gravity which pulls it towards the earth. Since this force and the horizontal component of the projectiles velocity are at right angles to each other, the horizontal component of the velocity is unaffected during flight . This explains the symmetry of the parabola and also means the time to reach the top of path equals the time from the top of path back to the ground. The projectile will hit the ground with the same speed as it left the ground. If you draw a horizontal line through the parabola, at the two points where the line and the parabola cross, the speed of the projectile will be the same. The only change to the balls speed during the flight comes as the vertical component of its velocity tends to zero as it reaches the top of the curve and then falling back down due to gravity. I'm unsure of your physics knowledge but hopefully this doesn't confuse you. If you have learned about vectors, then this can be simply understood/explained.
When an object At the highest point there's an instant when the motion is changing from upward to downward then what is its velocity?
At that moment, its vertical velocity is zero. Its horizontal velocity may or may not be zero, i.e., it may be moving sideways as well.
What will the velocity and acceleration be of a ball at its highest trajectory point just before it starts to fall?
The acceleration of the ball (after it leaves the thrower's hand) is the acceleration due to gravity, g.1 The vertical velocity of the ball at its apex is zero. The horizontal velocity is constant throughout the ball's flight; it is whatever it was at the outset of its arc.2 ---------------- 1. The acceleration due to gravity, g, is -9.8 m/s2 or -32.2 ft/s2. 2. Ignoring the effects of air resistance, which tend to slow things down.
What is the direction of oblique projectile at highest point?
Horizontal
What is the highest velocity of an airgun?
The highest velocity of an airgun is that of Evanix AR6 pistol which is 1000 fps.
