Whakaoti mō g
\left\{\begin{matrix}g=-\frac{u^{2}-v^{2}}{2h}\text{, }&h\neq 0\\g\in \mathrm{R}\text{, }&h=0\text{ and }|v|=|u|\end{matrix}\right.
Whakaoti mō h
\left\{\begin{matrix}h=-\frac{u^{2}-v^{2}}{2g}\text{, }&g\neq 0\\h\in \mathrm{R}\text{, }&g=0\text{ and }|v|=|u|\end{matrix}\right.
Tohaina
Kua tāruatia ki te papatopenga
u^{2}+2gh=v^{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2gh=v^{2}-u^{2}
Tangohia te u^{2} mai i ngā taha e rua.
2hg=v^{2}-u^{2}
He hanga arowhānui tō te whārite.
\frac{2hg}{2h}=\frac{\left(v-u\right)\left(u+v\right)}{2h}
Whakawehea ngā taha e rua ki te 2h.
g=\frac{\left(v-u\right)\left(u+v\right)}{2h}
Mā te whakawehe ki te 2h ka wetekia te whakareanga ki te 2h.
u^{2}+2gh=v^{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2gh=v^{2}-u^{2}
Tangohia te u^{2} mai i ngā taha e rua.
\frac{2gh}{2g}=\frac{\left(v-u\right)\left(u+v\right)}{2g}
Whakawehea ngā taha e rua ki te 2g.
h=\frac{\left(v-u\right)\left(u+v\right)}{2g}
Mā te whakawehe ki te 2g ka wetekia te whakareanga ki te 2g.
