What is the horizontal acceleration of a projectile?
The horizontal acceleration i.e. Vx throughout the trajectory remains constant only of the air resistance is neglected. The gravity can affect the y-component of velocity but is unable to affect its x-component. Acceleration (delta V) does not occur unless a change comes into play per Newton. Gravity does not effect x but air resistance would. Likewise, projectiles launched from e.g. an explosion experience a reducing delta V in that acceleration from an explosion is subject to the inverse square rule.
What are the horizontal and vertical components of the acceleration vector at the maximum height?
Neglecting air resistance, the components of acceleration of an object that's dropped, tossed, pitched, flung, lobbed, heaved, launched, or shot are constant. The horizontal component is zero. The vertical component is 9.8 meters per second2, directed downward. These are both constant throughout the object's trajectory.
What is the horizontal component of a vector whose magnitude is 70 and whose direction relative to the horizontal is 20?
A vector with magnitude = 70 , directed 20° above or below horizontal,has a horizontal component of70 cos(20°) = 65.778 (rounded)
How do you find vertical and horizontal components when given the initial velocity?
If the initial velocity is v, at an angle x to the horizontal, then the vertical component is v*sin(x) and the horizontal component is v*cos(x).
Can the vertical component of a vector cancel the effect of horizontal?
no.

A rifle bullet shot horizontally has a vertical acceleration of?
9.8 meters (32.2 feet) per second2 downward.
Is the horizontal component of a projectiles velocity independent of time?
Yes, in the absence of air resistance, which is the way the situation is always viewed by everyone except Navy gunners.
Which of the velocity component of projectile changes and other remain constant why?
the horizontal component remain unchanged because there in no acceleration in horizontal direction

How does gravity affect two componets of projectile motion?
Divide the motion into a horizontal and a vertical component. The horizontal component won't be affected by gravity. The vertical component will get a downward acceleration of 9.8 meters per second per second.
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 is the horizontal acceleration of a projectile as its position changes?
In the usual simple treatment of projectile motion, the horizontal component of the projectile's velocity is assumed to be constant, and is equal to the magnitude of the initial (launch) velocity multiplied by the cosine of the elevation angle at the time of launch.
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.
Why does a projectile maintain its horizontal component of velocity?
Because there's no horizontal force acting on it that would change its horizontal component of velocity. (In practice, that's not completely true, since the frictional 'force' of air resistance acts in any direction. But outside of air resistance, there's nothing else acting horizontally on the projectile.)
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.
How does gravity affect the 2 components of projectile motion?
-- Gravity causes the vertical component of projectile motion to vary according to the local acceleration of gravity. -- Gravity has no effect at all on the horizontal component of projectile motion.
