Question

multiple choice question
which statement correctly describes the view from directly behind the motion of a ball being thrown from one person to another?

the ball appears to move in a straight line forward.

the ball appears to move straight up, stop for a split second, then move back down

the ball appears to change horizontal direction suddenly, for no clear reason.

the ball appears to follow a parabolic path.

Explanation:

When viewing from directly behind the ball's horizontal motion, the horizontal component of the ball's movement is along the line of sight, so it is not perceived. Only the vertical motion (due to gravity, upward then downward) is visible, with a momentary stop at the peak height.

Answer:

B. The ball appears to move straight up, stop for a split second, then move back down
