We learned that for an object being thrown into the air, \( \vec{v}_f_y = 0 \frac{m}{s} \) at the top.
We also learned that there is symmetry for an object being thrown from the ground and landing back on the same ground.
Symmetry of a projectile
\( \Delta t_{up} = \Delta t_{down} \)
\( \vec{v}_{i_{y~up}} = -\vec{v}_{f_{y~down}} \)
\( \Delta \vec{y}_{up} = - \Delta \vec{y}_{down} \)
