A:
Well, assuming that were talking about a projectile thrown from the
surface of the earth, then while the projectile is in flight the only
acceleration it experiences is due to the force of gravity. (To be
precise, theres a little bit of other acceleration due to friction
with the air, but that vanishes at the highest point of a straight
up-down path because the velocity is zero there.) And the acceleration
due to gravity is constant on the object thoughout its flight. So the
acceleration of the projectile is equal to the acceleration due to
gravity, 9.81 meters/second/second, from just after its thrown, through
its highest point, and until just before it hits the ground.
If you search on the internet for projectile motion you will quickly find a ton of websites with little java appelets which demonstrate projectile motion. Many of these sites allow you to change certain variables, like the acceleration due to gravity, to see how they affect the projectiles motion.
Hope this helps,
