Formula e kiʻi i ka wikiwiki wikiwiki

\( v_a = \dfrac{v + v_0}{2} \ \ \) ma hea

\( v_a \) he wikiwiki wikiwiki
\( v \) he wikiwiki
\( v_0 \) ka wikiwiki wikiwiki

ʻO ka wikiwiki wikiwiki va = {{ result}}





Formula e kiʻi i ka wikiwiki wikiwiki

\( v_0 = 2 \cdot (v_a - v) \ \ \) ma hea

\( v_0 \) ka wikiwiki wikiwiki
\( v_a \) he wikiwiki wikiwiki
\( v \) he wikiwiki

ʻO ka wikiwiki wikiwiki v0 = {{ result}}





Kumumanaʻo e kiʻi i ka wikiwiki

\( v = 2 \cdot (v_a - v_0) \ \ \) ma hea

\( v \) he wikiwiki
\( v_0 \) ka wikiwiki wikiwiki
\( v_a \) he wikiwiki wikiwiki
