The ball would follow a straight line.
The rock follows a parabolic path.
speed and spin
its velocity will b zero....
Follow the invisible path it is in the shape of an S.
in vacuum the ball would continue at the velocity thrown forever. in an atmosphere the ball would gradually slow under resistance until stationary relative to the atmosphere.
It would go up
The direction of their motion changes, due to Earth's gravitation.
its velocity will be zero and acceleration will be -9.81 due to gravity
