What else can I help you with?
A projectile is fired horizontally from a gun that is 71.0 m above flat ground emerging from the gun with a speed of 250 ms What is the magnitude of the vertical component of its velocity as it st?
If it's fired horizontally, then its initial vertical velocity is zero. After that, the vertical velocityincreases by 9.8 meters per second every second, directed downward, and the projectile hitsthe ground after roughly 3.8 seconds.Exactly the same vertical motion as if it were dropped from the gun muzzle, with no horizontal velocity.
What part of projectile motion is affected by gravity?
Gravity affects the vertical component of projectile motion by causing the object to accelerate downward as it moves horizontally. This acceleration due to gravity affects the object's vertical displacement and velocity. It does not affect the horizontal component of projectile motion, which moves at a constant velocity in the absence of air resistance.
How can the horizontal velocity of a projectile be described?
The horizontal velocity of a projectile remains constant if there is no air resistance or external forces acting horizontally. This means that the horizontal component of the projectile's velocity does not change throughout its trajectory, only its vertical component is affected by gravity.
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.
When you jump upward your hang time is the time your feet are off the ground Does hang time depend on your vertical component of velocity when you jump your horizontal component of velocity or both?
Hang time depends on your vertical component of velocity when you jump. The higher the vertical velocity, the longer your feet will be off the ground. The horizontal component of velocity does not affect hang time.

If a rock is dropped and a ball is thrown horizontally at the same initial elevation Which will have the greater speed when it reaches ground level?
The thrown ball will have a greater speed when it reaches ground level because it has a horizontal component of velocity in addition to the vertical component. The rock only has a vertical component of velocity due to gravity.
A rock is thrown upward at an angle what happens to the vertical component of its velocity as it rises?
As the rock rises, the vertical component of its velocity decreases due to gravity pulling it downward. At the highest point of its trajectory, the vertical component of its velocity becomes zero before it starts to fall back down.
Is it true that the vertical component of the projectile motion of an object depend on initial velocity only?
Yes, in projectile motion, the vertical component of motion is influenced by the initial velocity in the vertical direction. The horizontal and vertical components of motion are independent of each other, with the horizontal component being influenced by the initial velocity in the horizontal direction.
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.
Does horizontal velocity effect the rate of vertical velocity?
No, horizontal velocity does not affect the rate of vertical velocity. Each component of velocity (horizontal and vertical) is independent of the other. They act separately to determine the motion of an object.
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
The vertical component of velocity changes due to the influence of gravity, which accelerates the projectile downwards as it moves. The horizontal component of velocity remains constant because there is no horizontal force acting on the projectile, assuming air resistance is negligible.
Why the horizontal velocity component remains constant and the vertical velocity component continuously changes during projectile motion?
The horizontal velocity component remains constant because there are no horizontal forces acting on the projectile (assuming no air resistance), so the velocity remains unchanged. The vertical velocity component changes due to the force of gravity, which accelerates the projectile downward, increasing its velocity as it falls.
