Is the acceleration of a projectile equal to zero when it reaches the top of its trajectory?

No, assuming no air resistance, there will be a constant downward acceleration of 9.8 meters per second square (assuming standard gravity).
The vertical component of the velocity will be zero at the top of the trajectory.

What is a freely falling projectile?
It is a projectile falling with an acceleration equal to that of free fall. (an object falling in a vacuum at the earth's surface)
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.
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 somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
What is contant acceleration?
motion of a body with constant acceleration, that means it has equal velocity in equal intervals if time.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.

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 contant acceleration?
motion of a body with constant acceleration, that means it has equal velocity in equal intervals if time.

Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
How is acceleration similar to speed and velocity?
-- The magnitude of acceleration is equal to the time rate of change of speed. -- The magnitude of acceleration is equal to the time rate of change of the magnitude of velocity. -- Acceleration and velocity are both vectors.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
What is the formula for forcemass and acceleration?
Force is equal to mass times acceleration. Mass is equal to density times volume. Acceleration equals to velocity over unit time.
What is maximum acceleration rate?
the acceleration is equal to energy that release by the friction that came be electic that travel form somewhere.It proves that maximum acceleration rate.The easy explainationof that is Energy and Velocity are equal to maximum of acceleration
What is the similarity between constant speed and acceleration?
If the speed is constant then equal distances are covered in equal intervals of time If acceleration is constant then equal change in velocity occurs in equal intervals of time.
The slope of a speed vs time graph is equal to what?
Acceleration.
