A projectile is launched from horizontal ground with an initial velocity directed at an angle above the horizontal and moves under the influence of gravity alone with negligible air resistance. Point \(P\) is a location along the trajectory while the projectile is ascending toward its maximum height. Which of the following diagrams correctly shows the directions of the projectile's velocity vector \(\vec{v}\), tangential acceleration component \(\vec{a}_t\), and normal acceleration component \(\vec{a}_n\) at point \(P\)?
