What is the vertical speed of a projectile at the top of its flight?
Zero.
The horizontal and vertical components of a projectile's velocity are independent of each other what does this statement mean?
That means the if you change one you do not necessarily change the other. In the case of the projectile the vertical component is dependent on time (if it is a projectile near a large mass like the earth) gravity acts on it accelerating the projectile in a downward direction. The horizontal component remains the same during the entire flight (if we disregard air resistance and such things).
How does ballistic refer to projectile motion?
The term ballistic refers to the trajectory or path taken by a projectile. Normally it refers to that part of a projectiles flight that is unpowered and unguided except by the forces of gravity and (if applicable) air resistance.
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.
How do you determine the range in a projectile motion?
Wind, elevation, trajectory, projectile weight, projectile configuration, barrel length, barrel rifling, friction or resistance in the barrel, force (charge) behind the projectile. There are other enviornental elements that can affect range as well.
Factors that affect the flight of the projectile?
factors

Which information is needed to determine the horizontal distance a projectile travels?
-- the initial horizontal speed of the projectile -- the time it remains in flight before it hits the ground
What angle for firing projectiles gives longest time?
45 degrees to the horizontal will give the maximum flight time for a projectile. If a projectile was fired at 90 degrees to the horizontal, (straight upwards) the projectile will go straight upwards (ignoring the shape, form and aerodynamic properties of the projectile). Likewise if you were to fire a projectile at 0 degrees to the horizontal, the projectile would follow said course, IF gravity was not in effect; a projectile needs some form of vertical velocity to overcome gravity. Hence why 45 degrees will give you the longest distance and consequently flight time.
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.
What is the definition of time of flight in physics?
the time taken by the body to archive highest point and returned to ground, is called flight o projectile.
Speed of projectile as it leaves a firearm?
Known as the muzzle velocity, it is the fastest speed the bullet will have in flight.
Which two angles gives the same range as 45 degrees?
If the question is in the context of the flight of a projectile, the answer is none.
Is duration of a flight a scalar or vector?
Scalars are quantities that are fully described by magnitude aloneVectors are quantities that are fully described by both magnitude and a direction.Duration of a flight is simply a magnitude and there is no direction so it is a scalar.
How do you find the time of flight of a projectile that lands on a lower elevation without using the quadratic equation?
Hello, In order to find the the time of flight of a projectile that lands on a lower elevation with using the quadratic equation, one must think deeply. In other terms, google search my friend. Thanks.
How does ballistic refer to projectile motion?
The term ballistic refers to the trajectory or path taken by a projectile. Normally it refers to that part of a projectiles flight that is unpowered and unguided except by the forces of gravity and (if applicable) air resistance.
