With air resistance, acceleration decreases. Without air resistance, acceleration remains the same throughout the fall ... the acceleration of gravity.
Answer:
D.
Explanation: Both have shapes determined by gravitational forces.
The projectile maintains its horizontal component of speed because there's nothing exerting any horizontal force on it. <em>(b) </em>
Gravity has no effect on horizontal motion.
That depends on a number of things that we don't know because you haven't told us.
If any of the things on this list changes, then the answer to the question changes:
-- What is "it" ?
-- Was it dropped, thrown, fired, or launched ?
-- From what height above the ground ?
-- With what speed ?
-- In what direction ?
-- What is the acceleration of gravity where this took place ?
-- Did any drag act on it, due to liquid or gas, before it hit the ground ?
