Why can a projectile maintain a constant horizontal speed when neglecting air resistance?
because of the mass of the object
Is the acceleration the same on an object that is drop or when its thrown?
It is the same (neglecting air resistance).
What do you need to know to be able to determine how far a projectile travels horizontally?
The horizontal velocity of the projectile (and the air resistance if known) will determine the horizontal distance traveled and the time required.
If you removed air resistance would objects fall with constant acceleration?
Yes. Neglecting the effects of air resistance, all objects near the surface of the earth fall with the same constant acceleration, regardless of their mass/weight.
What is the vertical acceleration of a projectile if the vertical component of its velocity vector is zero?
The vertical component of a projectile's velocity is irrelevant. It can be up, down, or zero, makes no difference. As long as projectile motion lasts ... gravity is the only force on the object and you're ignoring air resistance ... its acceleration is constant, and is equal to the acceleration of gravity: 9.8 meters per second2 pointing down.
If a projectile is shot in the air neglecting air resistance what is its vertical accelrration?
the vertical accelaration in case of a projectile is 'g'.

Ignoring air resistance what is the horizontal component of a projectile's acceleration?
Zero.
What is the acceleration of a projectile at the peak of its trajectory?
Assuming negligible air resistance, the acceleration of a projectile near the Earth's surface is always the gravitational 9.81 m/sec/sec downwards, regardless of where in the trajectory the projectile is.

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.
What is the vertical acceleration of a projectile if the vertical component of its velocity vector is zero?
The vertical component of a projectile's velocity is irrelevant. It can be up, down, or zero, makes no difference. As long as projectile motion lasts ... gravity is the only force on the object and you're ignoring air resistance ... its acceleration is constant, and is equal to the acceleration of gravity: 9.8 meters per second2 pointing down.
How do you find the acceleration of a ball that is being thrown as a projectile as it is leaving your hand... Just the acceleration as it leaves the hand?
After, and at the exact moment, the ball leaves the hand it is only accelerated by gravity if you disregard air resistance.
What is the horizontal displacement of a projectile?
it depends on the gravitational force of attraction of earth and air resistance. if we are neglecting air resistance, the max.horizontal distance is according to this formulae, V0/2 * sin (2theta) where V0 is the initial velocity theta is the angle with x axis and the projection.
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.)
