To a passenger on the train it will follow a parabolic trajectory facing towards the back of the train. To a man standing on the ground it will be a forward facing parabolic trajectory.

A projectile's trajectory is the curve along which it moves through the air or space. When a projectile is fired on earth the simplest theory holds that its trajectory will be parabolic in form. However, this does not account for air resistance and other factors.

the ofrmula is x=-b/ab... trust me in in 8th grade taking a 11th grade course!!

Actually, if you were to ask a Gunners Mate in the Navy, he'd tell you that the curved path of an object thrown is called a trajectory. And in a practical case, trajectories are not parabolic when traveled in a gas, like our atmosphere.

They are parabolic if and only if the objects are not also acted on by drag and angular momentum forces. And any good curve ball pitcher in baseball can prove that.

What is parabolic mean
