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 something
or falls to the ground.
The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greater
each second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the point
where the velocity transitions from upward to downward.

In projectile motion What Angle would horizontal and vertical distance be equal?
Can't say. It depends on the release velocity (muzzle velocity).The maximum horizontal distance always results from an angle of 45 degrees, regardless of the release velocity.
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.
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 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.
What are the two types of motion a projectile has?
If you throw ball at an angle above horizontal, you will see the path of the ball looks like an inverted parabola. This is result of the fact that the ball's initial velocity has a horizontal and vertical component. If we neglect the effect of air resistance, the horizontal component is constant. But the vertical component is always decreasing at the rate of 9.8 m/s each second. To illustrate this, let the initial velocity be 49 m/s and the initial angle be 30˚. Horizontal component = 49 * cos 30, Vertical = 49 * sin 30 = 24.5 m/s As the ball rises from the ground to its maximum height, its vertical velocity decreases from 24.5 m/s to 0 m/s. As the ball falls from its maximum height to the ground, its vertical velocity decreases from 0 m/s to -24.5 m/s. Since the distance it rises is equal to the distance it falls, the time that it is rising is equal to the time it is falling. This means the total time is equal to twice the time it is falling. This is the reason that the shape of the ball's path is an inverted parabola. At the maximum height, the ball is moving horizontally. If you do a web search for projectile motion, you will see graphs illustrating this.

Which factor has a significant impact on a firearm maximum projectile range?
velocity
How can you used trigonometry in projectile motions?
when a body is thrown at an angle in a projectile motion, the vertical component of the velocity is vcos(B) ..where v is the velocity at which the body is thrown and B represents the angle at which it is thrown.Similarly horizontal component is vsin(B). these components are useful in determining the range of the projectile ,the maximum height reached,time of ascent,time of descent etc.,
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.

At what part of the trajectory does a projectile have maximum speed?
The maximum speed of a fired projectile, unless fired downward in a vacuum, is the muzzle velocity - this is when the propulsive acceleration ceases. Ignoring air resistance, the projectile would maintain its horizontal velocity, while gravity would first reduce then restore the vertical component. Terminal velocity, the maximum possible atmospheric speed, is determined by mass, gravity, air density, and projectile shape, as gravitic acceleration is slowed by air resistance.
Which factor has a significant impact on a firearms' maximum projectile range?
Weight, velocity, and shape of the bullet.
What is maximum rang of projectile motion?
Suppose a projectile is fired from a gun, we know that "g" remains constant and as we use horizontal component of velocity in range sov0 also remains constant. Only sin2θ responsible for change in range. The range will be maximum if sin2θ has its maximum value that is 1.for maximum range:sin2θ = 12θ = sin-1 (1)θ = 90/2θ = 45 (degree)therefor if projectile is projected with the angle of 45(degree) its range will be maximum.
How do you find maximum height for a projectile without knowing the time?
Assuming the simple model where the object is projected with an initial velocity of u metres/second at an angle of x to the horizontal, and that the only force acting on it after that is gravitational acceleration, g = 9.81 metres/second^2, then h = [u*sin(x)]^2/(2*g) metres.If the launch is vertical then x = pi/2 radians and h = u^2/(2*g) metres.
When does a model rocket attain maximum height?
when the vertical component of its velocity is zero.
